I love the design of this bracelet: it looks kinda vintage and trendy at the same time. The wavy shape when it lays on your wrist may or may not work with stacking, though it might be a bit too delicate to wear on its own.
Each skull is about the size of a fingernail, but with intricately carved parts: you can even see sutures, mandible, and tiny teeth. This bone bracelet is beautiful and detailed.
