Blomdahl Medical manufactures safe ear piercing systems and hypoallergenic jewelry. Blomdahl jewelry does not cause nickel allergies because it is made of medical plastic with zero (0%) nickel content or pure medical titanium (Pure Medical Titanium). The part of the earring that does not have direct contact with the body is plated in gold or silver (Golden Titanium and Silver Titanium) and decorated with crystals. Blomdahl hypoallergenic earrings are recommended for people who want to be sure that wearing earrings will not contribute to the development of a nickel allergy (especially in the first year after ear piercing). Blomdahl jewelry can also be worn by people who are already allergic to nickel, gold or other metals and cannot wear any other earrings due to the annoying pain and itching that occurs.
