Material: Stainless steel L316 Chain length: Approximately 70cm Made with L316 stainless steel, this material is ideal for those with metal allergies. It also has the characteristic of being rust-resistant. Some metals, like silver, can oxidize and discolor due to air or sweat, or rust like iron. However, stainless steel is resistant to corrosion and heat, so it has the advantage of not deteriorating easily even with long-term wear. Stainless steel does not easily scratch or discolor, and requires no special care, allowing it to maintain a like-new condition for a long time. Material...Stainless steel
