I received this as a gift and have kept it stored away. It's in a Hiromi Art Shippo box, but the contents are different. Details are unknown. It can be worn as a necklace or a brooch. Two chains are included. One is silver 925. There is corrosion due to aging. The surface has some dullness. I'm not sure if this is part of the design or degradation (see image). Please refrain from purchasing if you are sensitive to used items. Feel free to ask any questions.
