Ita Bag: How to Make One and Why China Is Obsessed

Stand near the ticket gates of a metro station in Shanghai or Chengdu around 5 p.m. and you may spot one in the crowd: a pastel backpack with a clear, heart-shaped window. Behind the plastic are twenty badges of the same anime boy, arranged in a grid so neat it looks machine-made.

That is an ita bag. The style started in Japan, traveled through anime and gaming fandoms, and then found a huge new audience in China. Today, these bags do more than carry collections. They help turn character merchandise into a social activity and bring young shoppers back into malls.

An ita bag (痛バッグ, ita baggu, painful bag) is a bag decorated with pin badges, acrylic charms, photocards, or small plush toys. Modern versions usually place the display behind a clear vinyl window, protecting the merchandise while keeping it visible.

Below, you will find what the name means, the main styles, how to make an ita bag, where to buy one, and the part many English guides miss: China’s tong bao trend and the guzi economy behind it.

What Is an Ita Bag?

An ita bag is part bag, part portable display case. Most modern designs have three main parts:

• The base bag — usually a backpack, crossbody bag, or tote
• The clear window — a PVC or vinyl panel on the front, sometimes shaped like a heart, star, or television screen
• The insert — a removable panel behind the window; pins and charms attach to this instead of damaging the bag itself

Behind the window, fans arrange pin badges, acrylic keychains, small plushies, rosettes, and photocards. The plastic helps protect the display from scratches, accidental touching, and a small amount of moisture, although most ita bags are not fully waterproof. It matters when some pieces are limited editions or difficult to replace.

The point is devotion made visible. An ita bag tells strangers exactly which character, idol, game, or series owns your heart, at a volume no phone wallpaper can match.

What Does Ita Bag Mean in Japanese?

Ita comes from itai (痛い), the Japanese word for painful. It uses the same ita wordplay seen in itasha, the term for cars covered in anime and game graphics.

The original joke is usually understood as painfully embarrassing or painful to look at: the display is so excessive that it becomes self-aware. Fans later added two other explanations that fit just as well. The hobby can be painful for the wallet, and a large bag packed with metal badges can be painful for the shoulder.

Ita bags became widely visible in Japanese fan culture during the 2010s, before spreading internationally through conventions, social media, and online fandoms. The joke in the name remained, but its self-deprecating edge softened. For many fans, the elaborate excess became part of the appeal.

Ita Bag Styles: Backpack, Crossbody, Tote, and Shaped Windows

The best style depends on how much you want to display and how far you plan to carry it.

Pink, cream, lavender, and mint sit in the cute lane, while black lets bright merchandise stand out. Some bags add cat ears, lace, bows, or star-shaped windows. The display does not have to be anime-based either. K-pop photocards, video game pins, Disney collections, and tiny plush toys all work.

For a manageable first build, the STEAMEDBUN crossbody ita bag is a sensible base. It comes with an insert, has enough room for daily essentials, and gives you a useful display window without asking you to fill an entire backpack.

How to Make an Ita Bag

Most people buy the base and build the display themselves. This order saves the most rework:

1. Choose the base. Match the window to the collection you already own, not the collection you imagine buying. If you want an ita bag backpack, check the shoulder straps as carefully as the window.
2. Choose a theme. One character, one series, or one color story gives the display a clear direction. A mixed-fandom bag can work too, but some visual rule helps it feel deliberate.
3. Plan the layout first. Arrange everything on the insert before attaching it, then take a photo. That picture becomes your map.
4. Build in layers. Add background fabric or lace first, place the largest item, then work outward with badges and smaller charms.
5. Check the balance. Keep heavier items low, close the window, put your normal belongings inside, and walk around at home before taking the bag on a long day out.

Start smaller than you think. A small crossbody can look full with a modest collection. A backpack display is heavier, more expensive to complete, and much less forgiving of empty space.

How to Make an Ita Bag Insert

Many base bags include an insert. If yours does not, or the included board bends too easily, you can make one from plastic canvas, the stiff mesh used for needlepoint and other crafts.

Measure the clear window, then cut the canvas slightly smaller so it slides in without curling. Wrap it in fabric that matches your color scheme and secure the fabric at the back. The mesh lets pin posts pass through cleanly, while ribbon, elastic cord, and small safety pins can hold charms and plushies.

Cardboard can work for a display you rarely change, but plastic canvas is easier to rearrange and less likely to sag after repeated use.

How to Put Pins and Keychains in an Ita Bag

Push pins through the insert rather than the bag lining. Standard butterfly clutches may loosen when the insert flexes, so check each badge before carrying the bag. For valuable pins, you can also secure the post with a small piece of felt or use a locking back if there is enough space behind the insert.

Keychains usually behave better tied down than left hanging. Thread clear elastic or thin ribbon through the mesh and around each charm’s loop so the artwork faces forward instead of flipping over. For a plush toy, attach the tag or an existing fabric loop; avoid pushing a pin through the body unless you are comfortable making a permanent hole.

Then choose your layout. A grid places badges in even rows. A collage layers pins, ribbons, cards, and charms at different heights. Both can look intentional. The only real mistake is attaching everything before checking whether the window can still close.

Where to Buy an Ita Bag

• Amazon. For most readers, this is the best place to start as you can compare window measurements, included inserts, buyer photos, delivery dates, and return terms before ordering.
• Etsy. A good place to look for handmade bag bases, custom inserts, rosettes, and bags with lace or lolita-inspired details. Check processing and delivery times carefully if you need the bag for a particular event.
• Daiso. Useful for inexpensive display supplies and oshikatsu accessories when available. Selection varies by country, store, and season.
• In Japan. Ikebukuro and Akihabara are two of Tokyo’s best-known areas for anime and character-goods shopping. Retailers such as Animate sell ita bags, inserts, and display accessories, while fashion chains such as WEGO offer bag bases in different styles and sizes.
• Taobao. This marketplace offers a wide range of shapes and colors. Read photo reviews and check the exact dimensions.

That last option leads to the part of the story that deserves more attention. China is not only a major place to buy ita bags. It has developed its own language, display habits, and shopping culture around them.

Inside China’s Ita Bag Boom: Tong Bao and the Guzi Economy

In Chinese, an ita bag is tong bao (痛包), literally pain bag. The term arrived through Japanese fan culture, but the world around it in China now has a vocabulary of its own.

If half of that reads like code, it is. The wordplay and borrowed sounds are part of the same fast-moving world as Chinese internet slang.

The money involved is no longer niche. According to China Daily, data from iiMedia Research put China’s broader guzi economy — which includes badges, acrylic stands, cards, plush toys, figures, and other character goods — at an estimated 168.9 billion yuan in 2024, up 40.63 percent from 2023. The firm projected that the market would exceed 300 billion yuan by 2029. China Daily also cited a Xianyu report showing that users born after 1995 accounted for more than 70 percent of guzi transactions on the platform.

The same article offers some of the clearest evidence that this shift is reshaping shopping malls. In 2024, Shanghai’s Bailian ZX hosted nearly 700 events, recorded 13.3 million visits, and reported a 70 percent year-on-year rise in sales. What began as a niche collecting culture is now large enough to reshape physical retail and draw young shoppers back to established malls.

The ita bag sits in the middle of that economy because it turns every purchase into part of a larger project. A badge is not only a badge; it fills one more space in a planned display.

What Makes a Chinese Tong Bao Different?

There is no national rule for arranging an ita bag, and mixed displays exist everywhere. Still, Chinese fan posts often feature one especially recognizable style: dan tui, a bag devoted to one character, sometimes using many copies of the same badge in a precise grid. Collectors may also place each badge in a clear sleeve before attaching it, particularly when resale condition matters.

A useful clue, not a rule: a mixed-fandom collage celebrates several interests at once. A strict grid of one character turns repetition into the message. The second style is especially visible in Chinese tong bao culture, but neither belongs to only one country.

To an outsider, the duplicates can look accidental. Within the hobby, they show focus, patience, and spending power. One badge says you like the character. A whole wall says this is your character.

The format has also moved beyond anime. Fans build black tong bao around actors and idols, while joke versions display cash or even painkillers. Chiikawa, Crayon Shin-chan, Jellycat plushies, game characters, and characters from Chinese franchises can all appear in the same clear display window. The same small-purchase, big-feeling logic behind blind boxes works here too.

Why has it become so popular? Chinese discussions often return to emotional value (情绪价值, qíngxù jiàzhí). Domestically produced badges and acrylic pieces often cost far less than large figures, making them a relatively accessible way to buy a small piece of a favorite story. The purchase is less about practical use than comfort, identity, and belonging.

There is also a social layer. Fans trade duplicates outside guzi stores, look for a merch-hunting dazi on Xiaohongshu, and turn a shopping trip into an afternoon that ends with milk tea. It overlaps with China’s wider loneliness economy, but it is not simply about lonely people buying things. The bag makes a private interest visible and gives strangers an easy reason to talk.

Ita Bag Etiquette Worth Knowing

• Ask before photographing the person. The bag may be displayed openly, but its owner has not automatically agreed to be in your photo.
• Do not touch the window. Fingerprints are annoying, and the items behind the plastic may be rare or fragile.
• Name the character if you know it. A specific compliment feels much warmer than simply saying nice bag.
• Do not assume duplicates are available to trade. Ask first, and keep anything you offer clean and protected.
• Protect it from heavy rain. A PVC window can handle a few drops, but the seams, zippers, paper inserts, and fabric decorations may not be waterproof. In bad weather, use a clear rain cover that fits the whole bag.

Ita Bag FAQ

Does Daiso Sell Ita Bags?

Daiso stores in Japan commonly carry oshikatsu display supplies, but the exact bag range changes by location and season. Stores in the United States and other countries may carry clear display bags or accessories, but stock may be inconsistent. Check your local store rather than making a special trip based on an old social media post.

Are Ita Bags Only for Anime Fans?

No. K-pop photocard bags, Disney pin bags, game-themed bags, idol bags, and plush-only displays are all common. If an item fits safely behind the window, it can become part of an ita bag.

How Much Does It Cost to Make an Ita Bag?

There is no useful average because the base bag is often the smallest expense. A beginner can use merchandise they already own and leave breathing room in the layout. A repeated-badge grid built from limited items can cost far more. You do not need duplicates for the bag to count.

An ita bag sounds strange on paper: a handbag that is also a picture frame. In practice, it solves a very current problem neatly. It lets people carry proof of the thing that makes them happy and find others who recognize it.

Whether you are building a first crossbody for a local convention or planning a visit to Bailian ZX, the same advice holds: choose a theme, secure the pins, and make the display yours.
