Thank you for viewing! The material is also stamped. (silver925) This is a sample product. When shipping, we will inspect it and prepare a new one to send. We also sell necklace tops, so if you purchase them together, we will offer a discount. It was sold in stores for ¥8000. On sale at #maiseahawaii! This was sold in stores in Okinawa! Because it was not sold at a low price, it has a solid weight and is made of a material that is resistant to rust.
