OXO takes the guesswork out of measuring ingredients with its patented angled-surface cup that lets you read the markings along the side and or from above, by looking straight down into the cup. Sturdy plastic with soft, nonslip handles. Set of three includes 1-, and 2- and 4-cup-cap. sizes. Measurements are indicated in milliliters, ounces and cups. Dishwasher safe.
