Beautiful glasses! I'm not too much of a martini drinker but these are great for my negronis!  They hold about 6 ounces at capacity so you could use them for lots of kinds of cocktails. Sturdy without being bulky, they seem to be well made and I love the modern look! They were also packaged very well! They also have a cute little logo on the bottom that you can see from inside the glass which is fun
