I bought this at a handmade event. The artist is apparently well-known in that scene, and it was quite expensive, but it's truly cool. It's easy to wear and very lightweight. It seems to be made of real leather, and the lining is the original brown leather. (This was the case when purchased. Please see photos.) It has been stored in a dark place, so there is no damage, but as it was purchased 2-3 years ago, please refrain from purchasing if you are looking for perfection. The size is approximately 27-30 cm in diameter. It has an adjuster, so I believe it's free size. The height is about 7 cm. It will create a cool look for cosplay, cyberpunk, or gothic lolita genres. If you have any questions about the size or anything else, please feel free to ask. #GothicLolita #Cosplay #Leather #Punk #Cyberpunk #Choker #Necklace #GenuineLeather
