Keep Your Food Fresh Longer - A useful addition to any busy kitchen, the Work Wonder Sealing System keeps food fresh up to five times longer than ordinary storage methods like zipper bags, foil, plastic wrap, and containers. This system removes air and moisture while sealing in flavor so that your food tastes as if it was bought yesterday even after being in the freezer for months. Use it to freeze pre-made dinners to reheat for meals during the week, to keep left over salad or pizza slices in the fridge for later, to deep-freeze cuts of meat, and much more. Vacuum out the air to create a perfect air-tight seal!
