DO NOT BUY THESE GLASSES!!!!   These glasses have bubble in the glass with the bubbles on the inside of the glass (smooth on the outside).  When you stir a drink in them, the spoon breaks the glass over the bubbles and two things happen.  

One:  You drink the broken glass if you didn't notice it break (which we didn't).  

Two:  Deposits of drink mixes (in our case, Nesquick) build up in the open void where the glass broke.  Then, like us, you realize that the glass broke and you drank a piece of glass.

Put this warning out first, now we will contact the vendor and the consumer safety board to see how they plan to move forward.
