This is a bail made of surgical stainless steel (stainless steel 316L). It's a bail formed by press processing, with a thickness of 1mm, increasing both strength and appearance. It's not the weak type often seen, made by simply bending a thin plate that can be easily deformed by hand. ★Please refer to the images for the size. ★Offered as a set of 2 for 450 yen, including shipping. *Only regular mail shipping is available. ★Bulk purchases are a great deal!! ・～4 pieces (200 yen per piece) ・5 pieces～ (180 yen per piece) 900 yen～ ・10 pieces (160 yen per piece) 1600 yen～ ・20 pieces (120 yen per piece) 2400 yen～ *Please message us if you'd like to purchase in bulk! *Sets with different sizes are also OK! ★About Stainless Steel 316L Stainless steel is generally known as a strong and rust-resistant metal, but there are actually many types depending on the usage environment. Among the austenitic stainless steels with improved corrosion resistance, stainless steel 316L is particularly excellent in corrosion resistance. The "L" in 316L stands for Low Carbon, indicating a low carbon content, which reduces corrosion resistance. It is also a relatively rare type of stainless steel. Due to its high corrosion resistance, it is used in medical instruments and is sometimes called surgical stainless steel. Regarding metal allergies caused by metal ionization, the high corrosion resistance = low ionization properties make it suitable for jewelry as a metal that is friendly to those with metal allergies. Stainless steel 316 is used for marine sports and is seawater-resistant, and stainless steel 316L has even higher corrosion resistance.
