Review on SKQUE 12 Pack Extra Thick Reusable Storage Bags - Leakproof Seal Food Grade PEVA Sandwich Bags for Kids Snacks, Fruit, Travel Storage - BPA Free, Freezer Safe (4 Small, 4 Large, 4 Medium) - Enhanced SEO by Dana Johnson

How I accidentally found out how well they work: I put a bag of Annie's Cheddar Cheesy Smiles in the largest bag and placed in the pantry. I forgot for a few days, but when I finally remembered, I didn't want to try again, thinking cheddar smiles were outdated. nope! Still tasted like I just opened the packaging, that was a testament to how well they work. They also appear thick and sturdy. They seem like a good idea to use for on-the-go snacking or any other activity that requires you to rely on good containers. The only thing I didn't like was cleaning them all at once, but it doesn't take that long if you clean one or two at a time (I washed them as soon as I got them). But I'd rather complain about washing them by hand than continuing to put junk in there that needlessly kills life elsewhere on the only planet we have. They have no odor and this has not affected the taste of the snacks stored in them.
