What Causes Pin Damage in Ita Bags
Understanding the damage mechanism helps you choose the right prevention:
| Damage Type | Cause | Prevention |
|---|---|---|
| Surface scratching | Adjacent pins rubbing during movement | 5–8mm spacing between pins |
| Enamel chipping | Hard contact with another pin edge or window | Locking backs, proper spacing |
| Post bending | Lateral pressure when overpacked | Don’t exceed 80% insert density |
| Loose clutch / pin falling | Standard butterfly clasp vibrating loose | Locking pin backs |
| Fading / surface oxidation | UV exposure through PVC window | UV-resistant PVC, rotate display |
| Can badge surface damage | Pin post puncturing badge surface | Use badge covers on all can badges |
| Acrylic standee scratching | Standee tipping and sliding against window | Foam channel, velcro dot, foam pocket |
Locking Pin Backs — The Single Most Important Upgrade
Standard butterfly clasps (the silver butterfly that grips the pin post) loosen with vibration and movement. A pin worn or displayed for a full convention day will often lose a standard clasp entirely.
Locking backs types:
- Rubber/silicone clutch: Soft grip that holds through friction. Better than butterfly but can still loosen.
- Screw-on lock back: Post screws into the back — physically can’t fall off without deliberate unscrewing. Best for valuable pins.
- Locking lever back: Metal lever that clicks closed over the post. Reliable, easily removable for display rotation.
Rule: Replace standard butterfly clasps on any pin worth more than you’d be comfortable losing. Screw-on backs for the most valuable pieces. Locking lever or rubber clutch for the rest.
Badge Covers — Protecting Can Badges
Can badges (55–58mm printed badges with pin back) have a surface that scratches and scuffs easily. Limited-run event badges, Sailor Moon anniversary badges, and Jump Festa exclusives cannot be replaced.
Badge cover sizes:
| Badge Diameter | Cover Size |
|---|---|
| 44mm | 44mm clear cover |
| 55mm | 55mm clear cover |
| 58mm (standard) | 58mm clear cover |
| 65mm | 65mm clear cover |
| 75mm+ | 75mm clear cover |
A 0.15mm clear PVC cover adds minimal visible bulk and prevents:
- Surface scratching from adjacent pins
- PVC window fogging transferring to badge surface
- Fingerprint oils degrading the print layer
How to apply: Slide the badge into the cover from the back. The clear face sits flat over the badge print. Pin the badge-in-cover through your insert as normal.
For rosette assembly (badge in the center of a fabric rosette), seat the covered badge in the rosette mount — the cover protects the badge surface while the rosette fabric frames it.
Insert Material and Pin Safety
Your insert type affects how securely pins are held:
Foam inserts — best grip, most damage protection. Pin post pushes fully into foam and stays upright. The foam grips the post and prevents pivoting. Most popular choice.
Canvas/fabric inserts — requires rubber clutch or locking back on reverse side. Without a back, fabric pins will tilt and potentially scratch neighbors as the bag moves.
Velvet inserts — high friction surface keeps pins in place with standard clasps, but velvet compresses over time. Add locking backs for anything valuable. Velvet hides pin holes better than foam after rotation.
What to avoid: Stacking multiple items in a deep window without depth separation — pins at the bottom get pressed against the window by pieces behind them.
PVC Window and UV Protection
The clear PVC display window exposes your pins to ambient UV light. Over months and years:
- Soft enamel colors (especially pastels) can fade
- The PVC itself may yellow and cloud, reducing display clarity
Mitigation:
- Store the bag away from direct window light when not in use
- Rotate display pieces — don’t leave the same pins under UV exposure permanently
- Choose bags with thick (0.5mm+) clear PVC — thicker PVC holds its clarity longer and yellows more slowly
Packing and Transport Protection
For conventions and events:
- Remove acrylic standees before packing the bag into a suitcase or dense luggage — standees snap under pressure
- Wrap acrylic standees in microfiber cloth for transport
- Close the display window before putting the bag in a pack or bag — an open window lets pins contact other items
For storage:
- Never store pins in a bag face-down — the weight of items behind the insert presses pins against the window, grinding them together
- Store pins in a cork board, glass display case, or dedicated pin wallet during off-season rotation
- Do not store pins in original packaging bags — condensation can form inside sealed plastic over time
How to Protect Pins & Badges FAQ
Do I need locking pin backs on every pin?
No — use them on pins you care about. Standard butterfly clasps are fine for inexpensive filler pins. Prioritize locking backs on: rare/limited pins, event exclusives, most expensive pieces, and any pin that’s been loose before.
Can badge covers be reused?
Yes. Slide the badge out, clean the cover with a soft cloth, and reuse it on a different badge. Clear PVC covers last for years if not folded or scored.
How do I prevent pins from scratching each other in the insert?
Maintain 5–8mm spacing between pin edges — use a small cardboard spacer to gauge this consistently. Never let pins touch. Replace standard butterfly clasps with locking backs so pins can’t rotate and drag their edge against a neighbor.
My PVC window is yellowing — is that damaging my pins?
Yellowed PVC reduces display clarity but doesn’t directly damage enamel pins. However, the chemical changes in aging PVC can occasionally leave surface transfer marks on badges in direct contact with the window. Keep at least 10mm of space between your front pins and the window surface using insert depth, or use a thin foam layer as a buffer.
How do I safely remove a pin I haven’t moved in a long time?
Support the insert fabric with one hand while pulling the pin directly outward — don’t wiggle or lever it sideways. Foam inserts grip pins tightly; pulling straight out releases cleanly. For velvet inserts, use two fingers to slightly compress the velvet around the post before pulling.
