These are being punted as fidget spinner bearings but as most skaters will know they are the same size you use in your skateboard or roller blades. And I'm sure there are a heck of a lot of other uses. These don't get a ABEC rating you get with branded skate bearings but the average for ceramic is rated 9. And if you have never used ceramic bearings then there is no reason not to try at this price.
