You can personalize keycaps with photos, illustrations, logos, legends, or gradients. Provide clear, high-resolution artwork or an Adobe Illustrator file with your preferred layout; contact us for design-preparation help. After ordering, we prepare a design draft for your approval before production; you may request adjustments. Check your email and carefully review layout, artwork placement, and legends before approval. Listed mechanical keyboards support Bluetooth, 2.4 GHz wireless, and USB Type-C wired connections, with Windows and Mac layout modes; check the product page for model-specific details. RGB backlighting does not necessarily mean legends shine through. Front- or side-printed shine-through options are listed for Cherry-profile models; confirm availability on the product page. PBT keycaps use five-sided dye sublimation, so printed colors may differ slightly from screens or original artwork, and fine details may soften. The separate 100% 104-key custom membrane keyboard is a chiclet model with UV printing; printing options cover keycaps only or both keycaps and keyboard face. Mechanical-model PBT, profile, and hot-swap specifications do not apply to it.
