Built for collectors who want a clear decision.

If you’re choosing between Solid and Gradient: the construction stays the same — you’re mainly choosing the finish. Below are the practical details on compatibility, handling, and care.

PSA & CGC compatibility

Built as a precise PSA slab protector and CGC slab protector. If your slab is PSA or CGC, the fit is engineered around those standards.

Handling & stacking

Ideal for frequent handling or stacked storage. The frame structure helps keep contact points controlled — especially around edges and corners.

Easy care

Keep it clean with a soft microfiber cloth. Avoid harsh cleaners and reduce contact with abrasive surfaces to minimize fine marks.

Gem.Eleven slab bumpers are built as durable graded card protectors — a refined slab bumper and slab edge protector for collectors who balance structure and presentation.
