Thank you for viewing. Teacups Set of 5 Drinking rim diameter: approximately 8.5 cm These were gifts, but I haven't had many opportunities to use them, and they've been stored for a long time. I'm offering them to someone who will use them. There is no box or instruction manual, so I don't know the brand of the pottery. They feel rough to the touch. Please understand that they have been stored for a long time. Thank you.
