ABOUT US
GRANDMAT is a small crew of One Piece TCG players making the gear we wanted on our own tables.
WHY WE STARTED
We got tired of curling, glare-heavy mats that slid across the table mid-turn. So we designed our own: matte, deep-black, tournament-legal, and built to survive a full weekend of regionals in a backpack.
HOW WE BUILD
Every mat is dye-sublimated onto a low-friction cloth face bonded to textured natural rubber. Prints are produced in small numbered runs, then retired — no restocks, no watered-down reprints.
PLAYERS FIRST
Each design is tested at locals before it ships. If a surface doesn't feel right for sleeve slides and fast shuffles, it doesn't make the drop.
