This was a gift. I have a lot of glasses and these are new and unused. First one: Approximately 7cm in diameter, 8cm wide, and 8.3cm high. Second one: Approximately 6.7cm in diameter, 8.3cm wide, and 8.3cm high. Sizes are approximate. These are one-of-a-kind items. Please understand the characteristics of blown glass and the artist. Please also be aware of any scratches from the manufacturing process, pontil marks, or black spots that are typical of handmade items. Please refrain from purchasing if you are overly concerned about these details. I think they are a good size for tea, rock glasses, other drinking vessels, or vases for a single flower.
