We really like the style and durability of these Palermo cups made by Italian porcelain company, Nuova Point. They are bar-ware (espresso bar ware) and not fine porcelain. There may be some imperfections in the glaze; these are functional items, not museum-ware!

They come in traditional reddish-brown color with white interiors, are vitrified porcelain with incredibly thick (3/8" side walls) and very strong. Once heated, they prevent heat loss as you enjoy your true 5 ounce Cappuccino. If you want a Big Gulp, go to 7-11!
Sturdy and thick-walled. This size cup is used in many barista competitions now.

The cup stands 2½"  tall by itself and 2¾" when on it's saucer.
