These patented, double walled, self insulating, porcelain mugs are the most ergonomic cup on the market! They are hand use specific and hold approximately 10 oz. By design, Café-ERGO mugs follow the form of a cupped hand. The thumb is placed over the crescent flange and the fingers wrap around the cup. By eliminating the traditional handle, hand and finger stress usually associated with it is diminished or not there at all.
