To keep your food fresh and aromatic for even longer, simply seal it airtight in no time. This way, the vitamins, aroma, flavor, and freshness of snacks, delicacies, and much more are preserved for longer, and the treats still taste excellent days later. Just run the handheld sealer along the edge of the bag: the plastic bag is sealed airtight again without vacuuming. It is also perfect for freezing, as the sealer prevents freezer burn. Conveniently, the back of this small household helper is equipped with a magnet, allowing it to be easily hung on the refrigerator door. Foods like coffee beans and others retain their aroma longer. Simple and quick: reseal all bags airtight without vacuuming. Handy shape, magnetic back. Requires 2 AA batteries (please order separately).
