When I first replaced the cherry caps with custom caps, my keycaps were instantly different. We are a group of geeks who love custom keycaps, and we created the XDK brand because of our love. - We select high-quality PBT material for these keycaps to keep your keyboard fresh and not easy to produce dirt. - The outer surface of the keycaps is a very small grainy frosted texture, giving it a smooth touch similar to that of "ABS". - The dye-sublimation process makes the color of the caps better and not easy to fade. - Select the height of XDA to give your fingers a better touch, allowing you to enjoy the joy of typing. We take customer experience very seriously. If you find any missing or damaged key caps after receiving them, please contact us to handle it for you.
