Review on Enjoy Your Espresso In Style With CNGLASS Double Wall Glass Cups - Set Of 2 by David Urbanski

Very thin glass that breaks especially easy. You can look at the glass and tell it’s very fragile, but I am soft handed and careful with glassware and I broke both glasses back to back and ruined two fresh cups of espresso when I tried stirring in sugar and milk. Very disappointing to not only break my glassware so soon after buying, but to do so while I was trying to be careful to not break them. They were also too big for my machine (my fault, but something to consider) I had to remove the liquid catch to get the glass to fit every time.
