02 · The Case

A vessel as deliberate as the tiles.

Bead-blasted 6061-T6 aluminum, anodized to match the set you choose. A two-tier lift-out tray; every interior surface lined in vegetable-tanned leather. Each tile rests in its own recessed micro-suede slot.

Concealed aluminum hinges. A single magnetic seam — no visible clasp. The kind of object that asks to be opened with two hands.
