Review on Large Double Wall Insulated Glass Coffee Mugs With Big Handle - Set Of 2, 16 Oz. Jumbo Cups For Iced Or Hot Beverages, Premium PunPun Coffee Glasses by Kyle Gresham

I've had these for a couple of weeks now.I've used it to in my microwave to reheat my coffee and am glad to report that my coffee was nice and hot and the cup itself was cool to touch and I didn't need to worry about burning my hands.These are light in weight and the do feel a little plastic-y because they're so light. And whenever I flick my finger against it, it's definitely glass.I've used these for tea, followed by washing it out just with water and refilled with coffee. There was no residue of the previous drink (same when using coffee first, then tea). I think these will be little work-horse cups.I would buy again.
