Bananabell 4 x 13mm, 316L Surgical Stainless Steel.
This 4mm (6 gauge) bananabell is a curved 13mm internal diameter barbell machined in hypoallergenic surgical stainless steel. It is finished with 8mm ball ends.
Our stainless steel is a surgical steel with the 316L designation. Just like any other steel, this steel contains nickel. However, the nickel release rate for 316L surgical stainless steel is well below the allowable value given in the EU nickel directive, which makes it hypoallergenic and well suited to use in piercing studs and fashion earrings. This steel is also used for medical purposes, such as surgical implants, which remain in the human body for a lifetime without any harmful side effects.
