I am a big fan of Conquering, and I have way too many. This listing is for everything on the pic. Not selling seperately. If you are not familiar with the brand they specialize in fidget jewelry. The rings are sold as a base with a seperate spinner. In this listing are two bases a size 11 and a 12. The smooth one is 11 The bumpy one is a 12 The spinners are all different and unique. They fit both bases.
