This is a set of 10 white, round teacups, likely made in China, with a storage box. They are very thin and lightweight, and you can see your fingers through them. The material is unknown, but I believe it is either glass or plastic. They are unused but old, and the box is damaged, with torn fabric, so they are being sold as junk items. Diameter: Approximately 8cm Height: Approximately 4cm Weight: 20g - Set includes: 10 teacups and a storage box - Color: White - Shape: Round Thank you for looking.
