I received this from an acquaintance, so the details are unknown, but it's a glass dish with the beauty of stained glass. This small plate could be used as a tea coaster, coaster, or to display accessories and small items as interior decoration♪ Diameter: 10.5 cm Height: 1.5 cm The purchase date is unknown, and it was stored in a cabinet for a long time in its original box. The product box was stained and dirty, so I discarded it. However, I have a suitable replacement box, and I will pack it carefully to prevent breakage. Please feel free to ask any questions before purchasing.
