I bought re-usable vacuum seal containers from Foodsaver. I hate the thing. It cannot keep a seal and will always slowly let air in, in a few days. I keep looking for alternatives since I vacuum seal a lot and I hate using a new plastic bag for each, but have yet to find a suitable alternative that doesn't defeat the entire purpose.
