Stud Choker NecklaceMaterial Brass base with German Silver coating. The second picture in the gallery is an example of how it would look while stacking with a long necklace. This is a single choker neckpiece only. This necklace is handcrafted, and lead free so it won't cause a skin infection. We also get 2 3 layers of extra coating done on the pieces so that they don't tarnish over time. Fastening Hook. Care: > Keep in a plastic bag. > Keep away from fragrance and water.
