Poured frozen margaritas in these for a taco night and the 16-ounce size was perfect, no refills needed mid-meal. The cactus stem being colored all the way through means I can toss them in the dishwasher without the green fading.
The cactus stem is actually colored glass, not painted on, so I don't have to baby these in the dishwasher. They hold a full 16 ounces with room for ice, and the green stem makes them look way fancier than what I paid.
