J1 One-of-One USB Sim Racing Button Box Prototype - 8 Metal Buttons

ONE-OF-ONE J1 PROTOTYPE

• One-of-a-kind concept layout

Button assignments and compatibility depend on your PC, game, simulator, and control settings.

PROTOTYPE CONDITION

This is a working design concept, not a cosmetically perfect production model. It has visible 3D-print layer lines, seams, surface variations, small cosmetic imperfections, and four unused face openings, all shown honestly in the photos. These do not affect operation.

You will receive the exact controller pictured with its attached USB cable. No additional accessories are included.
