Review on Stay Organized With Colorful Double-Layered Mesh Waterproof Office File Organizers - 6 Pack B5 Sized Bags by Nick Singh

I bought the A6 and B8 size. Had problems with 2 A6 and 1 B8. 1 A6 zipper lead broke off, but I was able to find a substitute ring, and got the zipper working. the other 2 stuck at first, but with careful jiggling, they now run smoothly. It is hard to find these sizes in a zippered "envelope" format, and being water resistant is a plus. I would not submerge however, as the zipper would not be waterproof, but I feel confident it could withstand a rainstorm filled with electronics in my pants pocket. I will order a 2nd set and if my opinion changes, I will post an update.
