The size is approximately 12.3 x 12.3 cm. I am selling this as part of helping my parents declutter their home. This item has been stored unused. I believe the condition is good, but it has been stored for a long time, so please purchase if you understand that it is an old item. I have also listed several other items. If you purchase multiple items, I will do my best to offer a discount. I also offer combined shipping discounts. Please take a look if you'd like.
