This item came from my parents' house. I don't know the details. Diameter: Approximately 33.7 cm Height: Approximately 4.2 cm I don't know how often it was used, but it's old, so I think there is some aging. This is a used item stored at home, so If you are concerned, please consider carefully before purchasing. It will be shipped in a box stored at home. I am selling this as part of decluttering. I hope someone will use it.
