Hi and welcome to Robin's Nest! These very cool looking glasses are Russian vodka shooters (tall shot glasses). 5-3/4" tall, 1-3/8" across the base & almost 1" across the mouth. Thick, solid 1" clear glass base with a bubble in the middle. The set is in very gently used condition; a few tiny marks but nothing significant, no chips or cracks. Perfect for the vodka lover; however, this set also has a "sci fi" look so would be great for a science fiction fan or a scientist or medical professional used to working with glass test tubes. A captivating set sure to compliment your collection!
