Water-Resistant Polyester Ita Bag with Wide Adjustable Strap – 35cm Crossbody for Pins & Plush

Your Merch Deserves Better Than a Cracked Plastic Window

You’ve spent months collecting those limited-edition badges, handmade keychains, and rare acrylic stands. But the moment you pin them to a cheap fabric bag, the display window warps, the stitching pops, and you’re left embarrassed at the convention. Standard tote bags crush your plushies. Messenger bags have no secure back pocket for your wallet. And those “ita bags” from fast-fashion sites? They’re barely waterproof and fall apart after one wash.

Meet the 35cm water-resistant polyester ita bag – built by oshikatsu fans for oshikatsu fans. Every feature exists to protect your collection while making daily wear effortless.

Engineering That Protects Your Collection

• Reinforced Padded Insert Board: The included 19x26cm padded board gives your pins a stable backing that won’t sag or puncture. Unlike flimsy foam sheets, this composite panel keeps every badge perfectly aligned, even when the bag is fully loaded.
• Three-Layer Water-Resistant Polyester: Splash-proof exterior means you don’t panic when it starts drizzling at an outdoor festival. The fabric repels light rain while the internal compartment stays bone-dry.
• Wide Adjustable Shoulder Strap (up to 140cm): 3.5cm wide strap distributes weight evenly across your shoulder – no more digging into your collarbone after five hours of walking the dealer’s hall. Fully adjustable to wear crossbody or over one shoulder.
• Hidden Anti-Theft Back Zipper Pocket: Slip your phone, passport, or cash into the rear vertical pocket that sits flush against your body. Pickpockets can’t reach what they can’t see.
• Expandable Side Pockets with Elastic Cuffs: Each side pocket stretches to hold a 500ml water bottle or a folded umbrella. The elastic top keeps items secure even when you’re running for a panel.
• Double-Window Design: Clear Front Display + Internal Organizer: Show off your pins through the crystal-clear PVC window, while the main compartment houses your iPad, A4 notebook, and a 20cm plush without crushing anything.
• Detachable Weekly Planner Insert Board: The included “JENNY is th WEEKLY PLAN” board isn’t just for decoration – it doubles as a scheduling tool for convention events or daily school use.
• Four Metal D-Rings for Keychain Clusters: Hang your plush keychains, mascot charms, and LED light strings from the reinforced rings. No more fishing for keys at the bottom of your bag.

Who This Bag Was Built For

• The Convention Marathoner: You need a bag that holds your badge binder, water bottle, and six plush keychains without destroying your shoulders. The padded strap and water-resistant shell let you survive 12+ hours on the expo floor.
• The K-pop Photocard Collector: Your PC binder, light stick, and fan-made pins all need a dedicated display space. The clear front window turns your bag into a walking shrine – without damaging any merch.
• The University Otaku: You carry an iPad for notes, A4 textbooks for lectures, and a 20cm nendoroid doll just because. This bag fits all three while looking subtle enough for daily campus wear (choose khaki or off-white for low-key vibes).
• The Enamel Pin Trader: You buy, sell, and trade pins at every event. The padded insert board lets you swap out displays in seconds – no tools needed. Just pull the board, rearrange, and slide back in.
• The Cosplayer with a Crowd: You need quick access to your phone for selfies, a secure pocket for con cash, and a way to show off your character-themed badges. The back anti-theft pocket and front display window solve all three.

Why This Over a $20 Shein “Ita Bag”?

Cheap imitations use single-stitched polyester that unravels within weeks, thin PVC that yellows and cracks, and shoulder straps narrower than 2cm that cut into your skin. Worse, they omit the padded back panel – so your pins poke through the fabric and scratch your phone. This bag uses double-stitched seams, UV-resistant PVC, and a reinforced board backing. The side pockets are elastic-cuffed, not just open holes. The back pocket has a secure zipper, not a flimsy snap. And the insert board is included – a $10 value on its own. You’re paying for durability that survives three years of conventions, not three weeks of daily use.

Frequently Asked Questions

What are the exact dimensions of this water-resistant polyester ita bag?

The bag measures 35cm in length, 27cm in height, and 12cm in depth. The included padded insert board is 19cm by 26cm, designed to fit perfectly inside the clear front window for stable badge display.

Does this ita bag fit A4 textbooks and an iPad?

Yes, the main compartment is spacious enough to hold A4-sized textbooks, an iPad (up to 13 inches), a folding umbrella, and a 20cm plush doll simultaneously. The reinforced padded board prevents pins from poking through into the main compartment.

How many colors are available and which ones?

This 35cm crossbody ita bag comes in eight colors: black, blue, red, pink, purple, white, yellow, and khaki. Each color has the same water-resistant polyester construction and includes the weekly planner insert board.

Is the shoulder strap removable or adjustable?

The wide shoulder strap is fully adjustable up to 140cm in length, allowing you to wear the bag as a crossbody or over one shoulder. It is not removable but clips securely to reinforced metal D-rings on both sides.

Can this bag hold a 20cm plush doll along with pins?

Absolutely. The clear front window is for badges and pins, while the main compartment has enough depth and height to carry a 20cm plush, nendoroid doll, or similar collectible without crushing or distorting the display window.

Is the material truly water-resistant?

The 300D polyester composite fabric is treated with a water-resistant coating that repels light rain and splashes. It’s not fully submersible, but your pins and electronics stay dry during unexpected drizzles or accidental spills.

Quality Commitment

Every bag is cut from 300D polyester composite fabric, assembled with lock-stitched seams at stress points (straps, D-rings, pocket openings), and tested for zipper pull strength. The PVC window is acid-free and scratch-resistant. The padded board uses high-density foam that won’t crumble. This is a bag you’ll still use after your oshi graduates.
