Material: Stainless Steel Size: 8mm ball [Stainless steel is a metal that is resistant to heat and corrosion, and does not easily oxidize. Because it has very high hardness, it is resistant to scratches and easy to care for. In addition, it hardly dissolves metal ions, which are the cause of metal allergies, so it is a material that people with metal allergies can wear relatively safely.] 10mm size is also available.
