Sore piercings? Niobium is the #1 option for new or sensitive piercings. Even the most sensitive ears are comfortable in Niobium, as it is the least likely metal to cause an allergic reaction. ~Hypoallergenic, 100% lead-, latex-, and nickel-free niobium posts ~Perfect relief studs for sore or new piercings ~Choice of single earring or pair ~Choice of anodized green, blue-teal, or purple-violet ~Includes snug-fitting silicone backs ~Tiny, 2 mm heads ~21 gauge posts ~Posts are approx. 10 mm long (Need a different length? Let me know!) ~Handcrafted in the USA The colors of anodized niobium are essentially a patina - chemically stable and won't fade over time. Anodized colors are especially cool because they can change slightly in varying light (see pics). Love, love, love them. :) Thank you for shopping at Sweet Lobes! ©2021 Sweet Lobes.
