The OXO Good Grips Citrus Squeezer is designed to look like a traditional juicer taking the guess work out of how to properly insert the fruit. Just place the lemon or lime half into the bowl face down and squeeze the handles to fully extract the juice. The Citrus Squeeze is constructed of strong, die-cast aluminum coated with a non-stick finish and has non-slip, pressure-absorbing handles. Dishwasher safe.
