I purchased this snack box (set) {ninja pattern} for my son to use for his morning snack at school. If you haven't noticed the dimensions, it is not a full size lunch box, but is meant for snacks. It is insulated so it will keep cold for the couple of hours or you can fit a smaller ice pack in there. I am really happy that I found this so I don't have to use a full size for just a snack, or a tupperware that won't hold the cold for as long as I need it to.The smaller lunch/snack bag really is very small, we haven't used that yet.The only thing I would like to see is more designs, but would recommend!My daughter uses this for her puppy to hold her lunch for obedience training days. The small zippered container holds the exact amount of food for lunch, and it and a bag of snacks fits into the larger zippered container. And who doesn't love dinosaurs. Highly recommend.Really wanted to love these. The Dino design is adorable but these bag end up being useless quickly. Lost the first zipper on 1 bag within a few uses. They were used for less than 3 months and now all zippers have broke on all 5.Perfect size for my preschoolers snack boxThis product provides everything I need out of it. My only gripe is that it’s a little large. Other than that, totally worth every penny!Smaller than anticipated. More of a snack bag than a lunch bag but works for our needs!Love these! Wish I'd bought them sooner!There’s are in no way leak proof, but hold dry goods fairly well, chips and crackers and such. I like to take them to work. The print is cute and fun, holds up well.I have bought other resuable snack bags before, which you have to press the plastic strip at the top to reseal it, however my 5 year old struggled to do it.The content could have easily fallen out into his school bag.This design with the zip is perfect. The bigger bag sizes are used for sharing snacks with his friends.Even my 2.5 year old can open and close the zip without any issue.The quality seems good and the design is cute.Other parents have commented on it and really liked them.Great sizes, take a while to air dry so having multiples is awesome
