X-raypad Obsidian Control Mouse Skates Universal 0.8mm PTFE Donuts (32-Pack)

Obsidian DIY Mouse Skates feature 9.5mm diameter mouse feet made from hardened PTFE for improved control and stopping power.
The surface is hard and micro-frosted, effectively increasing surface friction for better control and stopping.
Suitable for cloth and glass mouse pads, not for coated or plastic mouse pads.

Universal donut type that can be used with any mouse.
The fewer soles you attach, the less friction there will be and the faster it will be, but the more soles you attach the more friction there will be and the slower it will be, so use according to your preference.

Compared to the dot type, there are more bumps, which improves control.

The inner part of the donut can be removed to suit your taste.
The inner part has a diameter of 4.3mm and is removable, so you can use it as a stabilizer if you like.
