Few days ago I went to seal up my latest haul of smoked cheese. Open my last box of food saver rolls And found them useless. They were full of creases and folds. So, I went on line and found this pack of two rolls of 8" wide by fifty feet each 4mil thick bags for 18.95 with free shipping. The reviews all point to be that this product works very well. The shipping was very fast. Got them in two days. I'll be using them Saturday. Has anyone else tried these?
