I bought a set of 6 whiskey glasses and a set of 6 Bohemia diamond water glasses. They are very sturdy glasses, they have a nice weight, and they fit well in the hand. They don't slip because the diamond design is deeply embossed. I usually wash them by hand. I have had them for 5-6 years and they haven't had any issues. I had planned to buy the rest of the glasses in the same series (tall glasses), but unfortunately, I didn't like them, I wanted something more delicate.
