these glasses are very sturdy, they hold 16 oz. the color is nice. Being hand blown each one is uniquely colored. that being said there is a place on the bottom of each glass where the glass blower ended and some of them have a nub For me it's not a problem. Also the clear part of the glass is not crystal clear but has a slight amber shad to it. Also not a problem for me. All in all a nice sturdy "non run-of-the-mill" glass! Love them...........oh, but they did take al LONG time to get to me as they are coming from Mexico. If you can wait I recommend.
