This item came from my parents' house. I don't know the details. Diameter: Approximately 32.3 cm Height: Approximately 3.2 cm I don't know how often it was used, but it's old, so it likely shows some age-related deterioration. Please consider this a used item stored at home. If you are concerned, please consider your purchase carefully. It will be shipped in simple packaging. I am selling this as part of decluttering. I hope someone will find a use for it.
