This product is keycaps only, not a keyboard. You can replace your mechanical keyboard keycaps with these keycaps for an enhanced look and comfortable touch. The surface undergoes a grinding slip process, providing a smooth finish with good anti-slip performance and improved feel. These keycaps are compatible with various standard mechanical keyboards.

Alternatively, use needle-nose pliers to gently adjust the cross stem, clamping slowly and with patience. To remove tight keycaps: Use a flathead screwdriver to carefully pry around the cross stem, applying gentle pressure and patience.
