FoodSaver Small Fresh Zipper Bags 26 x 950ml 4 "Handy sized bags designed for vacuum storage of food" Ms Cunniffe 28 October 2020 No problem with these but not sure how many times they can be used to ensure the vacuum seal remains 100% effective. Instructions for use do not indicate this. They would be very expensive if you cannot use them more than 3 times. They are designed to be used with the Foodsaver vacuum storage machine. So ...if you want to use the machine it does appear you have to have the Brand name bags. You Tubers offer an alternative route but the bottom line is cheap zipper bags would be unreliable . I like this product but suggest that they are used sparingly because of the expense. A note from the team These can be washed after each use and re-used numerous times.
