Grail Guards

Grail Guards — Engineered for the Cards That Matter

The grails in your collection didn't come easy. They shouldn't sit in plastic.

The Edition One Grail Guards are precision-engineered aluminium display cases, machined to fit PSA slabs with the kind of tolerance you'd expect from a watch case, not a card holder.

Designed in London for serious collectors who've outgrown off-the-shelf displays, every Grail Guard is built to a single standard: make the card the centrepiece, and let the engineering disappear.

Built around your slab. The internal cavity is milled to PSA's exact dimensions — no slip, no rattle, no compromise. Your slab sits flush, framed, and fixed. The aluminium chassis gives it weight, rigidity, and a finish that holds up under shop lights, show lights, and shelf lights alike.

Designed to be seen. The proportions are deliberate. The bezel is clean. Nothing competes with the card. Whether it's a vintage rookie, a modern 1/1, or the chase you waited years to land, the Grail Guard frames it like the centrepiece it is.

Specifications:

• CNC-machined aluminium frame
• Engineered specifically for PSA slabs (not compatible with BGS, SGC, or CGC)
• Precision-milled internal cavity for an exact, flush fit
• Premium finish, hand-checked before dispatch
• Designed in London by Edition One

For the collector who's stopped buying packs and started building a collection, our Grail Guards are the upgrade your grails have been waiting for.
