Floral Pattern Pair Mug Cups with Crazing Size Diameter: 8.5cm Height: 8.8cm Weight: 198g 209g They have a cute design. There is no instruction manual, so we don't know the type of firing, but since there is crazing, please avoid using them in the microwave. It looks like it might be hand-painted. The dark blue parts of the pattern are raised and have a smooth, glossy finish. The handle is slightly indented (concave) so that fingers can easily fit and it feels comfortable to hold. (Photos 13, 14) They are stable. They were stored in this box, but the height is insufficient, causing the lid to float, so this box will not be used. We appreciate your understanding for items kept in home storage.
