These Pavina Double-Wall Thermo Glasses are handmade by Bodum. The glass is mouth-blown, so each glass has a slightly unique shape. The double wall insulates the liquid inside, which means your beverage retain its temperature longer. The double wall also prevents condensation and excess heat from reaching your hands.
The glasses get good rating from buyers — over 700 Amazon buyer rated these glasses 4 out of 5 stars. However, the glasses are somewhat delicate, so if you are rough with your drinks, you might want to look elsewhere. Buyers do report that Bodum will often replace the glasses if you break them.
