This item came from my parents' house. I don't know the details. Diameter: Approximately 45.5 cm Height: Approximately 7.0 cm I don't know how often it was used, but it's old, so it has aged to some extent. This is a used item and has been stored at home, so please consider carefully before purchasing if you are concerned. It will be shipped in simple packaging. I'm selling this as part of decluttering. I hope someone will use it.
