Features: Made with an acrylic base material, the keycaps are blank. The switches can be removed and interchanged from the acrylic base. This Cherry MX switch tester provides the same press feel as a mechanical keyboard using Cherry MX switches. With 9 different switches included, it helps you identify your preferred switch type. Each switch is clearly labeled on the board, making it easier to distinguish between similar-looking switches such as Grey Tactile, Grey Linear, Clear, and White. Mounted on a crystal-clear acrylic base and equipped with 9 translucent ABS keycaps, this switch tester allows you to easily see the color of each switch. It can serve as a stylish desktop decoration and is also a great tool for relieving nervous energy or anxiety. You can remove the switches and use them on your own keyboard at any time.
