DIY Hardened PTFE Donuts Bigger Footprint, More Stable Glide

The Obsidian Donut Mouse Skates are universal 9.5mm hardened PTFE donuts a wider contact footprint than the standard 6.5mm dots, for more stable mouse movement and less noise on the slide. The hard, finely frosted surface increases friction at the contact point; the hardened PTFE adds braking power for emergency stops and tap-shot precision.

Apply as many or as few as you want. Fewer donuts = faster glide. More donuts = more control and slower stop. Tune your skates the way you tune your sensitivity.
