Preserve unopened packs with stable humidity, protective sleeves, careful boxing and minimal handling.
Collector checklist
Keep packs away from heat, sunlight and high humidity.
Use archival sleeves, team bags, rigid boxes and dividers that do not compress wrappers.
Store slabs upright with room to prevent scratching and cracking.
Do not flatten a pack aggressively to make it look better. That can damage seals and corners.
Sealed packs should be treated as condition-sensitive collectibles. Do not open a pack for curiosity if the value depends on sealed status, and do not rely on a single seller claim when edge details, wrapper condition or slab information are unclear.
