The bags come in a roll or you can pay more and buy them pre-made. You can use any bag in this model, you can even use regular plastic if you use a strip of the vacuum bag so you can suck the air out. There's a vid on youtube about that. I order bags from Amazon, and it's cheap. You can also soux vide in these.
