About this Product
(Pictured print is WSF Polished. It slides on quite pleasantly!)
Default inner diameter is roughly a ring size of 6 (16.5 mm). Please send us a private message if you would like a different size and we'll get that version added to our shop asap. The price increase associated with using the co-creator for sizing just isn't something we want to stick anyone with.
