This set of 2 4oz. espresso cups combines a small serving format with double-wall 18/8 stainless steel and vacuum insulation. The cups are made for espresso shots and can also serve latte, Americano, cappuccino, CafeMocha, Irish coffee, tea, ice cream, juice, smoothies, and other drinks. Compared with ceramic lining, the stainless steel lining is more durable, odourless, less likely to break, and better at retaining hot or cold beverages. Leakproof lids and stainless steel straws support portable use, while the stackable shape saves kitchen space. Dishwasher safe and suitable for most espresso machines, the cups work for home preparation, travel, or professional barista service. Color: Assorted Colors.
