Eating healthy isn't always easy. That's why we designed a fresh Lettuce Keeper. The adjustable vent controls air circulation to help keep produce fresh longer. Recommended moisture settings for 16 common produce items are listed on the container for easy reference including lettuce, grapes, broccoli and carrots. The Lettuce Keeper can be divided in half with an included divider and when not in use, the divider stores in the lid. The base is smartly designed to hold water for additional moisture if needed or to allow water to drain away from foods. The keeper doubles as a colander for a one-step wash & store.
