Mistake 1: Buying a Bag Without Checking the Window Size
The window is everything. New collectors often buy based on the bag’s overall aesthetic and only realize later the window is too small for their collection.
The fix: Measure your largest piece of merch first. Add 3-4cm on each side for breathing room. That’s your minimum window size. See our size guide for detailed fits.
Mistake 2: Not Using an Insert
An ita bag without an insert is a bag with loose pins rolling around inside a window. They scratch each other, scratch the window, and fall into unflattering arrangements.
The fix: Every ita bag build needs a display insert — a padded surface your pins attach to. Most YourItBag bags include one. If yours doesn’t, check our inserts collection for compatible options.
Mistake 3: Overpacking the Display
New collectors want to show everything at once. The result: a chaotic, cramped window where nothing is visible.
The fix: Less is more. A curated display of 10-15 pieces looks more intentional than 40 pieces crammed in. If you have a lot of merch, rotate your display weekly. Leave visible space between pieces — it makes each piece more visible, not less.
Mistake 4: Ignoring Window Shape vs. Merch Type
Round window bags are beautiful but they’re not great for photocards. Heart-shaped windows suit pins but distort flat rectangular items. Square windows work for almost everything.
The fix: Match the window shape to your primary merch type.
- Photocards → flat rectangular window
- Pins and badges → most shapes work
- Plushies → deep rectangular window
- Mixed display → square or wide rectangle
Mistake 5: Using Alcohol or Harsh Cleaners on PVC Windows
This ruins PVC permanently. Alcohol causes PVC to crack, yellow, and become brittle. Once it starts, it can’t be reversed.
The fix: For PVC windows, water only — or very diluted mild soap. For acrylic windows, mild soap and water is fine. See our cleaning guide for full instructions.
Mistake 6: Not Protecting Expensive Pins
Standard pins scratch easily during movement. Limited edition, expensive, or irreplaceable pins lose their finish within weeks of unprotected display use.
The fix: Badge covers — transparent dome caps that fit over standard 25mm and 58mm pins. They’re inexpensive and protect the pin face completely. Add them to your valuable pieces before the first wear.
Mistake 7: Choosing Bag Style Over Function
The coffin-shaped bag looks incredible online. But if you’re carrying it to school every day, a novelty shape with no main compartment will make you miserable.
The fix: For daily use, prioritize function first: main compartment size, strap comfort, weight. Then choose the most aesthetically fitting option within those constraints. Save the statement-shape bags for events and displays.
Mistake 8: Buying a Bag Without Checking the Strap
You will wear this bag. For hours. A thin plastic strap on a bag loaded with heavy merch digs into your shoulder by hour two.
The fix: For daily carry, look for padded straps or wide fabric straps. For backpacks, padded shoulder straps are non-negotiable. Check the strap material in the product specs.
Mistake 9: Placing Photocards Against PVC Directly
PVC and printed card surfaces don’t mix well over time. Direct long-term contact can cause ink transfer from the card to the window, and the window’s surface can dull print finishes.
The fix: Always sleeve photocards before placing in the display. Standard 60×90mm card sleeves cost almost nothing and completely prevent this issue.
Mistake 10: Not Cleaning After Conventions
Conventions leave a film of dust, skin oils from brushing crowds, and general grime on your bag. Closing the bag without cleaning seals all of that inside with your merch.
The fix: After every convention, wipe the window, clean the fabric exterior, and air out the insert before packing away. It takes 10 minutes. See the cleaning guide for steps.

Frequently Asked Questions
Q: What is the most common ita bag mistake beginners make?
The most common mistakes are buying a bag with the wrong window size and skipping the insert. The window needs to match your merch dimensions — too small and your collection won’t fit; too large and pieces look lost. The insert is essential to hold pins in place.
Q: Can you fix an ita bag PVC window that’s been damaged by alcohol?
Unfortunately, no. Alcohol damage to PVC is permanent — it causes yellowing and cracking that can’t be reversed. Prevention is the only option: use water or diluted mild soap only on PVC windows.
Q: How do I know if my ita bag window is PVC or acrylic?
Press gently on the window. PVC is slightly flexible and soft. Acrylic is rigid and glass-like. PVC is more sensitive to chemicals; acrylic is more scratch-sensitive. Both should be cleaned with mild soap and water.
