These ceramic bearings are amazing! They play just as smooth as you would expect a ceramic bearing should. Longer life, faster/smoother run time, and self-lubricated. The bearing is constructed with ceramic balls and stainless steel races so they won't rust. These bearings are now stocked in all limited edition runs that are exclusive to clywstore.com.
They are .250"x.500"x.188" in size and are perfect for unresponsive play.
