OXO's adjustable measuring cups will put an end to battles with peanut butter, honey and other sticky ingredients. An internal track and a comfortable turning knob allow the plunger in the body of the cup to adjust smoothly to the desired measurement marking. Simply fill the cup with your sticky ingredient, and turn the knob to push it right into your mixing bowl. The plunger acts as a squeegee on the inside of Cup, getting out every last bit of your ingredient. OXO adjustable measuring cups can also be used for wet and dry ingredients, eliminating the need for multiple sizes of measuring cups and spoons scattered throughout your kitchen. The generous rim makes pouring ingredients easy. Measurement markings are in English and metric units. Dishwasher safe.
