Purchased from an antique shop in Prague, Czech Republic, and kept at home unused because I didn't want to use them. This is a set of two. They are from the Czechoslovakia era, and I didn't know the brand when I bought them, but according to an internet search, the pattern is called Blue Onion. I think the decoration on the top (like vertical stripes) is stylish. I found them at an antique shop, so I don't know if they were used in the past, but since I haven't used them since I bought them, I've listed them as "new and unused." I think they are in good condition. Cup diameter (drinking surface) 8.5cm x height 7.5cm I checked them carefully, but I am a novice, so I may have missed something. Please consider purchasing only if you understand that they have been stored at home. I will wrap them in bubble wrap and ship them via Rakuraku Mercari delivery service.
