Observe exact measurements as you fill the glass. OXO Good Grips 2 contains markings for cups, ounces and milliliters. A patented inclined surface allows you to read the measurement marks by looking directly into the cup and eliminates the need to fill, check and adjust the amount of liquid being measured. The handle is soft and non-slip for a firm grip. The various units of measurement capable of satisfying any recipe are printed on the glasses. The product is dishwasher safe.
