Performance Screw Knobs
For anyone who's lost one of these you know how nice it would have been to have a couple extra around. Especially good to throw in the brush bag for teams that go spieling regularly. They fit any brush with a Performance head (Performance Brushes, BalancePlus Brushes, Ultima Carbon Fiber Lite, Asham / 8-ender w/ Performance). Available in red or black.
