Graded Card Storage Box for Top Loaders and Slabs - Large Capacity

In this review the MIXPOET Graded Card Storage Box stands out as a practical storage solution for collectors who need substantial capacity and strong protection. Designed for sports and gaming cards, the case's single biggest strength is its balance of volume and protection: it can hold hundreds of top loaders or dozens of graded slabs while locking them inside a rigid aluminum-alloy frame lined with EVA foam. The reviewer found it useful for consolidating loose top loaders, One Touch holders and PSA/CSG/BGS slabs into one portable, lockable box.

Key Features

• Ultra-large capacity: Can store roughly 300 top loaders, about 85 One Touch holders, 78+ graded slabs or 1700+ loose cards, making it suitable for large collections.
• Maximum protection: A rigid aluminum alloy frame with ABS panels and EVA lining keeps cards and slabs secure and cushioned from impact and movement.
• Foam divider system: Fifteen soft foam dividers prevent sliding and collisions when the box is not full, keeping slabs upright and snug.
• Graded card compatibility: Sized to accept PSA, CSG, BGS, SGC and similar graded slabs as well as sleeved cards and top loaders.
• Portable and lockable: Lightweight with a carry handle and a key lock plus two spare keys for added security during transport or storage.
• Clear slot sizing: Internal slots sized about 8.6cm x 24.3cm with 10.4cm depth to reliably fit 3x4 in top loaders and common slab holders.

Who It's For

The MIXPOET storage box is ideal for card collectors who need to move or store moderate to large quantities of top loaders or graded slabs and value a rigid, lockable case. It works well for sports card collectors, MTG players who archive sleeved cards, and anyone consolidating graded slabs from multiple storage locations.

Collectors who want a soft bag, or a decorative display case rather than a transport/storage solution, should look elsewhere. Also, buyers should note that the package contains only the storage box and dividers; top loaders, One Touch holders and graded slabs are not included.
