Material: 316L Stainless Steel Width: 7mm Length: 50cm Surgical stainless steel refers to medical-grade stainless steel. Among over 200 types of stainless steel, this material has extremely low allergenic properties, making it less likely to cause metal allergies and very gentle on the human body. Therefore, it is used in medical tools such as scalpels and scissors. It is resistant to rust and discoloration even when exposed to seawater, and it is a very hard material, making it resistant to scratches. I purchased this last year, but I haven't had much opportunity to use it, so I am selling it. Please understand that this is a used item.
