KEYGUARD®

Slab Case Protector

Your slab case is the only thing standing between the world and the book inside. KEYGUARD is a premium slab case protector designed to give that case a real layer of edge protection, without changing the way the slab looks, stacks, or displays.

The slab case is the weak point

Graded comic slab cases are rigid, but the corners and edges chip under normal handling. A slab case protector wraps exactly those surfaces in TPU, absorbing the daily impacts that quietly downgrade the look of a slab over time.

Universal across grading companies

KEYGUARD is designed to fit CGC, PSA, and CBCS slab cases under one universal profile. One protector, three grading companies, hundreds of books.

Display-ready, ship-ready, show-ready

Snap the protector on once and leave it on. Integrated wall-mount slots support flathead-screw display. The same protector works in a long box, in a carrying case, and in the mail.

The materials philosophy

Premium thermoplastic polyurethane. Firm. Quiet. Long-lasting. The same material family used in flagship phone cases, applied to the slab case the way it should have been from the start. Compatible with CGC, PSA, CBCS, and most modern graded comic slabs.
