YYJ Shims

Shims by YoYoJam are built to offer a way to increase the gap width of your YoYoJam keeping it fixed at a larger size than normal. What this does is help make the yo-yo unresponsive since a wider gap means the string is less likely to grab the yo-yo while it is in the middle of a string trick.

Each shim set comes with two shims to go on either side of the bearing in the yo-yo.

Please note there are two thicknesses - the gray set is thinner while the red set is thicker.
