This item came from my parents' house. I don't know the details. Diameter: Approximately 32.0 cm Height: Approximately 3.2 cm I don't know how often it was used, but it's old, so it likely shows some signs of aging. Please consider this item carefully before purchasing, as it is a used item and has been stored at home. It will be shipped in simple packaging. I am selling this as part of a decluttering effort. I hope someone will find a use for it.
