The Zambumon Sar is a compact keyboard that combines the functionality of a full-sized keyboard with a sleek, efficient design. It features a winkeyless compact 1800 layout, providing dedicated areas for number input, navigation, and typing, all arranged for optimal usability. The keyboard's aesthetic is refined and purposeful, showcasing clean lines and attention to detail, making it a stylish centerpiece for any workspace.

The Sar is built with a 4.75mm thick plate and a fully-isolated gasket mount that incorporates vibration-dampening urethane strips, enhancing the typing experience. Users can choose between a polycarbonate or brass switch plate, each offering a distinct feel. The WT90-A circuit board is designed for ease of use, featuring hot-swappable sockets for quick assembly and RGB LEDs for layer information. It is also QMK compatible, allowing for customizable programming through VIA.

Available in four striking finishes—Momentum Red, Pwner Soul Black, Lightning Silver, and Samurai Blue—the Sar is constructed with beadblasted and anodized aluminum enclosures, complemented by an internal black brass weight.
