The Bulwark TKL is a tenkeyless mechanical keyboard designed by Garner, featuring customizable color-matched wrist rests that can be purchased separately. The keyboard utilizes a white H88 PCB designed by Hineybush, which comes pre-flashed with a daughterboard and JST cable. It offers RGB underglow lighting that can be configured for both static and shifting colors, and supports hotswap ANSI and ISO PCBs, as well as a solderable option.

The Bulwark TKL is built with an isolated top mount design, using adhesive custom gaskets to separate the PCB plate from the keyboard top, ensuring a solid typing experience without flex cuts. The keyboard has a typing angle of 6°, a front height of 19mm, and weighs 2kg. Its case is constructed from aluminum 6063 for the top and frosted polycarbonate for the bottom, providing a durable and aesthetically pleasing finish. The wrist rest, made from aluminum and frosted polycarbonate, measures 373mm in length, 82mm in depth, and 17.5mm in height.
