These work great! Personally I usually tend to go to off-brands or store brands because they are the cheaper option... And most times I regret it! These Ziploc bags are the perfect size for regular leftovers or snacks/lunches. The seals work great and are much easier than the ones you have to peel apart. I use them for packing lunches, leftovers and freezing items... Since picking these up I have actually been able to store sauces and more liquid foods in them without leaks!
