These Brass Curb Chain Hoop Hinged Ear Weights are sold in pairs and handmade for a unique look. Each ear weight measures about 30mm x 30mm and weighs 13 grams. Crafted from high-quality casted brass, the hinged design clicks together to stay closed. Minimum gauge size should be 2G (6mm). Due to the material, brass may oxidize under extreme moisture conditions - long-term wear is not recommended.
