The size is approximately 32cm in diameter for the bottom plate. I am selling this to help with decluttering my parents' house. This item has been stored unused. I believe the condition is good, but it is an item that has been stored for a long time, so please purchase it if you understand that it is old. The box has some damage. I have several other items for sale. If you purchase multiple items, I am trying to offer a discount. I also offer combined shipping discounts. Please take a look if you'd like.
