Easy to use, a quick way to vacuum seal food with no fuss. Reusable I have reused bags over 10 times and they still seal.These work well with the Nesco hand-held vacuum as long as you make sure they are completely sealed using the Ziploc-like closure. Interestingly, these bags say that you should handwash them only, yet the Nesco hand-held vacuum says that they are dishwasher-safe. Regardless, I handwash mine -- it seems like too much of a waste to use once and toss. They aren't always the easiest to clean, though, and I don't expect to use them more than a few times apiece. Already I've had one bag get stained by messy food, and I don't feel confident that it's fully clean.These bags (and the system) are great for prolonging the life of deli meats, cheeses, and leftovers as long as they aren't too messy. The system is much more convenient than using a full-size FoodSaver for those kind of foods. I love that I can open the bag, take something out, and reseal it without a big production.-- Debbie Lee WesselmannThe bags are perfect for me as I break food down into single servings. I am very happy with these bagsThis vacuum system is not the cheapest bags, but for years has supplied me with the ability to keep foods and goods well sealed for much greater life in cabinets, closets, in the fridge, and in the freezer.Loose their suction after a day or twoPretty good and you can see what’s inside of your bag No waste anymoreLoose vacuumMy wife loves this product.

De type zip-lock, ils sont offert en deux formats pratiques.Parfaits pour les aliments secs. Résistants. À laver immédiatement, sinon la moisissure s'installe dans la pastille.
