This set includes a glass cake dome and a wooden base, perfect for beautifully preserving desserts. The inner diameter of the glass case is 23cm, and the height is 10cm. I'm not sure when I purchased it, but I haven't used it much and it's been stored for a long time. There are no scratches on the glass case. There are some minor scratches on the wooden base, but they are not noticeable. In addition to storing whole decorated cakes, as you can see in the attached photos, you can also use the case and base upside down as a salad bowl for a large group. Thank you for looking.
