I am looking for a factory to produce a custom metal numpad for a luxury French brand. The design requires a 12-key layout with a warm copper or brass finish—no standard stainless steel. We're targeting a premium look with backlit white LEDs shining through custom key legends, which should feature our specific characters instead of standard numbers. Also, could you confirm if you can create the numpad in a warm tone finish, whether solid brass or via PVD coating? Additionally, we need to ensure that the key legends can be fully customized, either through engraving or laser etching. Let me know if this is feasible!
