When you get dirt into your Ceramic Super REDS, the ceramic balls will help to re-polish the steel races flat again, providing a self-healing benefit because ceramic balls are so much harder than steel. Finally, ceramic balls will not rust, further lengthening their life.Ceramic Super REDS use a bone colored shield with laser-engraved outer races for identification.
