Charm LATEX SILICONE RUBBER WRIST BAND WITH STAINLESS STEEL

A latex or silicone rubber wrist band with silver stainless-steel parts is typically a bracelet that combines:
A flexible latex or silicone rubber-like band — soft, waterproof, and comfortable for everyday wear. Silicone rubber is popular because it’s durable and hypoallergenic. 

Silver-colored stainless-steel hardware — often a buckle, clasp, or decorative metal segment — that adds structural durability and a sleek look. 

These are fashion accessories, not to be confused with exercise resistance bands used for fitness workouts (which are typically long latex bands with heavy stretch resistance). Latex/silicone bracelets don’t offer significant strength resistance for workouts.
