I bought these bags to use with my Severin Vacuum Sealer. This is quite a big size, and I experimented with making one bag into two. It works really well.
Seal the open end, but the bag into two (in the middle), and proceed to seal in the normal manner. Voila!
2 bags from one bag. This is useful if you would like to seal small food items or small portions rather than large ones.
I would recommend this product to a friend.
