How to store trading cards to prevent damage

The three storage rules

• Stable environment: avoid humidity and temperature swings.
• No surface contact: sleeves prevent scuffs and fingerprints.
• No pressure points: avoid tight binders, overfilled boxes, and heavy stacks.

Environment: humidity and temperature

Humidity is the #1 long-term enemy, especially for foils. The goal is consistency. Avoid storing cards in basements, attics, garages, or near windows. If you use sealed bins, don’t trap moisture inside; start with a dry environment and check periodically.

Pick the right protection level

Binder tips (if you use binders)

• Use quality pages and avoid overfilling.
• Store binders vertically like books (not stacked under weight).
• Avoid tight rings that pinch pages.
• Keep grit out; dust can create surface scratches over time.

Handling habits that prevent scuffs

• Handle by edges when possible.
• Use clean hands; avoid lotions/oils before handling.
• Don’t slide cards on hard surfaces; lift instead.
• Use microfiber only if you know the surface is clean (grit + rubbing = scratches).
