This is a men's stainless steel ring made from 304L and 316L hypoallergenic stainless steel. It is made to order and offered in sizes : 8-13 1/2 in increments of 1/2 sizes, This particular ring i made by doing a side by side cut big enough to hand twist 316L inlays and welded them in place. Its very strong due to the properties of stainless steel and hypoallergenic as well. All of my rings are made by hand and because of this they are all one of a kind! Due to it being stainless steel it can't be resized. Ships in 5-7 business days. Want a matching set, i also make a womens version of this ring. Check out the set offered in my shop listings.
