Bumper is a standard 60% four-post tray-mount keyboard case.

Bumper is a sturdy, rounded keyboard case that is inspired by our love of pinball. It has removable side pieces that we call "flippers" and a 4-post mounting system. This Round 2 pre-order will feature a smoky black polycarbonate body design and sandblasted copper flippers. Special when lit!
