Product Description

The Bever Products metal center caps are the best upgrade for your fidget spinner!
Grab a set and install in seconds to improve your spin game.
Plastic caps wear out but metal will last forever.

Will it fit my spinner?
If you have 608 or R188 bearings in your spinner it will fit.
Most all spinners on the market use one of these two bearings.
Take note in the pictures that the inner part of the button has 2 sizes. One for 608 and the other for R188.
Installation Instructions
Seat one of the caps inside the bearing to prevent side to side movement.
After seating one side you can easily screw in the other side and you''re done!
