Review on ☕ PunPun Clear Coffee Mugs - Double Wall Glass Espresso Cups with Big Handle (380ml, Set of 2) by Justin Boisvert

I recieved the set of glasses but one of them had a few scratches on the outside glass. Since it is only one of them, I didn't want to return the whole set. I called Revain customer service and they sent me a complete new set and asked that I keep the good one from the original set. Great customer service! As to the glasses, it holds 16 oz of tea or coffee. Since it is double panned, it doesn't sweat and definitely keep your beverages hot longer. However, it you are like me that use a tea warmer, it will just keep the outside of your cup warm but not the 2nd layer glass, nor your beverage in the glass.
