I was really looking forward to receiving these. When they arrived, I was shocked to find out that due to the way they had been packed that all of the storage pockets were deeply bent on one corner, where the zipper part is located. I did my best at bending them back and then sat a heavy object on them for almost a week, before they straightened out, somewhat. This could have been avoided, due to the amount of storage pockets that were shipped, if they'd been put into a different shipping envelope.
I have started using some of them and like the zipper effect, but I have found that stamps that could fit into one of the pockets is limited on entering the pocket due to the zipper top, as opposed to an open concept. Other than that, they are a great quality and will last for a good while.
