Surgical stainless steel is called "316L" in the JIS standard and is a material with extremely low allergenicity among stainless steels. It is also used in medical tools such as scalpels and scissors, as well as body piercings. These are less likely to cause metal allergies because the metal ions that cause metal allergies do not dissolve. ② Rust-resistant Surgical stainless steel is a material that is resistant to oxidation, so it is rust-resistant and less likely to discolor. Stainless steel is originally made rust-resistant by alloying chromium with iron, which covers the surface with an oxide film called a non-conductive film, making it less likely to oxidize. Therefore, it has the characteristic of being rust-resistant. ★ Please understand that this is a used item. ★ Please look at the images carefully and confirm. 　 The box in the image is not included!
