Eat healthier this summer by adding fresh fruits and vegetables to your diet. And keep those fruits and vegetables fresh longer by storing them in Clever Fresh Vacuum-Seal Canisters. Extend freshness and prevent food discoloration by removing air with the Clever Fresh Manual Pump. All canisters are BPA-free and stack for convenient storage in your pantry or refrigerator. Place the manual pump over the fresh lock button on the canister lid, pump 4-5 times, and your contents are sealed. Its that easy!
