this is ALU40, the first ever wireless true ortholinear mechanical keyboard designed by huibenLAB in collaboration with polarity works to complement apple devices. at 24-28mm tall with exclusive work louder mx keycaps, it's also the slimmest ever keyboard with full height mx switches while still fitting a large 1800mah battery originally designed for iphone for months of uninterrupted use. the bead blasted finish, typing angle, and other details perfectly match peripherals such as magic trackpad and studio display. the pcb is suspended on a plate mount enclosure machined from a single block of aluminum, with a subtle rgb backlit transparent bottom edge. hand assembled by me and shipped from brooklyn ny.
