This is an antique item with a gorgeous floral pattern and mother-of-pearl inlay carving. When light is shone through it, a see-through pattern appears. You can appreciate the quality of the craftsmanship of the past. The 8th image shows the see-through pattern from the front, and the 9th image shows it from the back. The see-through parts and the mother-of-pearl are very beautiful, and I think it can still be used. Thank you for looking.
