Bat Wing Studs: Brass or Copper

I always wondered if bats felt like they were hugging themselves in a giant blanket with their wings.  A comfy embrace, like these cute handmade silhouette bat wing studs.  Choose from either brass (yellow colored) or copper (red-pinkish colored), backs/posts are sterling silver.
