Brand new, unopened. Set of 2 mouse skates. Includes 40 dot skates, 2 cleaning pads, and 2 adhesive remover wipes.

This is quite troublesome. It's easy to forget to remove the protective film, which affects usage. Suitable for cloth and glass mousepads. Not suitable for plastic mousepads. Thickness: 0.8-0.9mm. The 6.5mm diameter, 0.8mm PTFE dots provide better control and stopping.
