Stainless steel is a very durable metal, and shows itself best in our ring collection.  No need to baby these - they can be freely worn while swimming, gardening, in the shower, tossed in a box with loose change....and will be none worse for wear. 
TIP: In most cases, our rings are somewhat adjustable in size, though difficult to make a significant size change without proper tools.  Always order a size a bit snug as it is easier for you to open up the ring than to size it down.
