For most food items, sealing them up in a Tupperware container is fine and will preserve them for a decent amount of time. But what if you're just crazy about food preservation? What if you're looking to eat your leftovers from last night sometime next spring? Well then, you've got to get every bit of air out of that container. And that requires an over-the-top gadget.
The Lock & Lock Vacuum Sealer creates a, you guessed it, vacuum in your food container, keeping things fresh for longer. Apparently, it was designed for females, but I don't see why men wouldn't also enjoy sucking all of the air out from around their half-eaten sandwiches.
