It was stored in a storage closet. I am selling it because I will no longer be using it. Diameter: Approximately 13.5cm, Height: Approximately 6cm Important points: * I washed the entire item before listing it. * Each piece has its own unique pattern, with slight variations. * There is a mark on the bottom, but I couldn't read it. * There is no box. I will pack it with bubble wrap and ship it via anonymous Mercari delivery. * Returns are not accepted after purchase, so please check the photos for any concerns or ask questions in the comments before purchasing. I will answer as best as I can. Please understand that this is a used item that has been stored in a warehouse before considering a purchase.
