I enjoy my espresso in a few sips vs. a shot to the back of the throat.  So I like glasses that keep hot drinks hot long enough for me to enjoy them. These double walled glasses (mugs) are perfect for that.  They are specially designed to be self-insulating, they maintain the correct temperature of whatever I serve in them. 

These little feats of glass-blowing magic are beautifully shaped.  They were designed by world renown Matteo Thun and are hand-blown by artisans. Just right for the hands to wrap around.  Delicious way to enjoy an espresso - at the beginning of the day or to end it.
