Is surgical stainless steel okay for people with metal allergies? Can I take a bath while wearing it?

Surgical stainless steel is also attracting attention as a material that is less likely to cause metal allergies.

However, in hot springs, depending on the ingredients, it may rust, so be sure to remove it before bathing.
