MK's competition grade Pro Rings come in 24 unique hardness and thickness combinations so you can dial in the exact feel and sound you want from your mechanical keyboard. MK's Pro Rings are constructed from high grade Silicone to offer crack resistance, superior elasticity to EPDM, and the most consistent feel.
MK Pro Rings come with a 1 year full replacement warranty.
To install: Carefully remove the keycaps from your MX switch keyboard. Place the O-ring around each keycap stem and roll it as far down the stem as you can. Proceed to carefully place the keycap back on the switch stem and gently press down a few times to fully seat the O-ring.

Please use caution when installing O-rings. MK is not responsible for any damage caused to switches, stems, or keycaps during keyboard modifications.
