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

Bought on a whim. Not a name brand, but works well and looks nice. Convienient for hot(cool to touch) and cold drinks (does not sweat) , seems to be genuine borosilicate glass i.e. can tolerate boiling water/hot coffee with out breaking. Really light weight, looks like it will break easily if dropped. Smooth easy to clean, made of glass so does not have plastic taste. Good value. Claims to be microwavable, but that's probably pushing it. Seems fragile ( hand wash only).
