These are nice glasses. However, the diameter of the glasses are narrower than the measurement listed in the description and I was trying to match ones that I already own. I was informed that because they are hand-blown, the sizes vary. I purchased two sets (12 total) and ALL of them were narrower than the description. The company worked with me and sent out another set of six, so that I could pick the best ones. Still none of them met the size listed. They said I could send them all back for a full refund if I wasn't satisfied. I ended up keeping 12 even though they don't match my old glasses, and sent back the 6 smallest ones. The company was great to work with and I'm sure I will buy from them again if I find more products I like.
