Package Contents: You will receive 500pcs O-rings, giving you plenty to spare even with a large extended mechanical keyboard.
These O-rings should be nearly all mechanical/gaming keyboards compatible with Cherry MX switches and keycaps. Please pay attention to the size to avoid inappropriate fit.
Place an O-ring on each keycap to reduce key travel and reduce the "clicky" noise that high-quality mechanical keyboards can produce.
Material: The O-ring is made of silicone material, which is elastic, tough enough and not easy to break.
Dimensions: 10mm outer diameter, 5mm inner diameter, 2.5mm thickness, thicker than most other O-ring dampers for more effective reduction of noise and key travel. An O-ring is a clear, translucent material that allows light to pass through. This means that if your Cherry MX keyboard has an LED light, the O-ring will not block the LED light.
