O-Ring For G3/G4 Timer (2-Pack)

The O-Ring is a circular rubber ring that can be placed on top of the power/reset buttons on the SpeedStacks G3/G4 timer to make it harder to accidentally reset or turn off the timer while solving. It can be glued down with super glue to make it a more permanent feature of the timer.

Each item is for 2 O-Rings.
