Know before you buy
POM is a softer, more flexible material than aluminum or steel. Using this plate will result in a less firm, slightly cushioned typing experience that reduces finger fatigue during long sessions.
Yes, the POM material produces a deeper, more muted sound profile compared to the sharper, metallic resonance of steel or aluminum plates. It is an excellent choice if you prefer a 'thockier' acoustic signature.
Yes, these plates are precision-cut to accommodate standard Cherry MX style switches, including most third-party mechanical switches that share the same mounting footprint.
Yes, minor surface scratches are common due to the nature of the POM material and the laser-cutting process. These marks are purely cosmetic and will not impact the structural integrity or performance of your keyboard.
These plates are specifically designed for the BM40 layout. We do not recommend attempting to use them with other 40% keyboards, as the mounting points and switch cutouts may not align correctly.
