This was a gift. ◎ Made with 316L stainless steel This material is known for being "rust-resistant" and is one of the least allergenic stainless steels. Also, because it's stainless steel, it's water-resistant, doesn't discolor, and won't rust, which are its main features. It's the perfect material for accessories that you can cherish for a long time. You can also wear it in the bath or while playing sports!
