The main material is some kind of stone, but I don't know the details. I'm not sure about the details or condition, so I'm selling it as being in poor condition. If you're interested, please take a very close look at the images and be sure you're satisfied before purchasing. It will be shipped via Yu-Packet Plus in a dedicated box, with the box placed in a bag, wrapped in bubble wrap, and cushioned with newspaper. I would appreciate it if you could read my profile before considering a purchase. I am not accepting price negotiations. Thank you for your purchase. Thank you for reading to the end. #Heart-shaped #Small container #Details unknown #Stone material
