Hi and welcome to Robin's Nest! This is a great cactus-shaped shot glass, beautiful green color, ribbed sides. 2-1/2" high, 2" across the top and 1-1/2" across the base with a good, solid 3/4" thick bottom. I'll call it "used" since I don't know it's history, but I can't find a mark on it. This would be perfect for tequila lovers! It's beautiful!
