I just purchased these reusable storage bags. I do like the quality of the material that is used to make these bags. They have a really good seal on them. Plus they also have a little clip that you can make sure you get it sealed really well. I'm there's two different sizes there's a snack bags with your kind of large and the sandwich bags which are even larger. I would definitely recommend these bags for purchase for the price I think it's a pretty good deal. I wish they had a size in between the small and the large style. Oh yeah it also comes with this little brush that you can clean it out with like so you can get into the little corners.
