The Reynolds' Handi-vac is a handheld vacuum sealer which works to keep your foods safe from freezer burn and maintain freshness. The Handi-Vac works with specialty bags that have a small air valve in the top right corner. You place the Handi-vac suction directly on the air valve and suck the air out of the bag until the bag becomes tight around the food. Once everything is sealed, you can freeze the food and keep it fresh for much longer than a non-vacuumed bag.
