These are antiques I inherited from my parents' home. They are about 100 years old. There are 5 in total, but since one has a scratch, I will price them as 4. I don't know the material, but they are very light. I will give you all 5. The one with the scratch isn't that noticeable and is still usable. They will be shipped in a recycled box. Thank you for your understanding. Dimensions: Length and Width: 14.5 cm each Height: 2 cm That's all.
