Curva Artisan Series Double Wall Beverage Glasses and Tumblers - Unique 8 oz Thermo Insulated Drinking Glasses, Set of 4

I love these for espresso; they keep my espresso nice and hot mmm.... I haven't had any problems -- some of the reviewers had problems with water leaking into the inner layer through the bottom. There is a bump there where the glass was sealed -- held my under water -- no problems. The glasses also came with contact information and a promise of replacement if there were problems. These are glass and are well insulated -- a freshly pulled hot shot doesn't burn fingers and is comfortably held in this glass. Holds a pretty good size double-shot and is wide enough to catch a double pour without spilling. These are awesome for drinking double-shot espressos without burning your fingers. Feel good in the hands! Great Price. These espresso cups are very useful in their ability to keep the coffee warm while one drinks it; they are also very beautiful, and pleasant looking. Moreover they are very sturdy as well. These are adorable and functional. They have little grip grooves that make it easier to hold on to when making espresso drinks. These also keep the espresso very hot. I have not tried them with cold shots, but I am sure they work just as great with cold drinks.
