This item is made with the finest type of medical-grade 316 stainless steel. It features a "Premium Finish", which means it is more shiny than stainless steel termed "Standard Finish". Premium Finish undergoes additional polishing processes which result in a brighter color. It can be worn at all times, because this shine won't fade or tarnish. Please note that all stainless steel contains small amounts of nickel.
