i have no idea how/why we go through so many zipper storage bags in this house, but we do. it's an enduring mystery. all sizes too, from the little snack sized all the way through the gallon sized. so when i saw this product from the 24/7 Bags store i jumped at it. what you get is a large box of 250 gallon sized bags. this is a FANTASTIC value and these bags are of outstanding quality. 2 mil thick, which means they're as thick as the heavy duty contractor trash bags i use, except here they're for food. they're double sealed and the seal is very secure. when i first got these of course i had to test how leakproof they were so i filled it with water and sealed it up. many strong shakes later, i am very happy to report that not only did the bag stay perfectly sealed, it didn't leak at all. and of course that means if it keels liquids in, it's going to keep air out... i love that there's a section for labeling, and i love that these are bpa free. just take one from the box, put whatever you need to seal up inside, close the double seal and tuck it away into a fridge or freezer. couldn't be easier and these are every bit as good as the major brands. better, actually, since i don't think those are as thick as this bag. i love these bags and think they're one of the best values going. the only thing to keep in mind is that this comes with 250 of them, not the typical 18 or 20 you find in stores, meaning the container is quite large (nearly a foot in length and width and maybe 5 inches tall) and therefore won't fit in a drawer somewhere. still, i'm buying these from here on out...
