I purchased these for storing my CTMH stamp sets. My sets fit perfectly. It's so much easier to see what I have at a glance. My binder sits nicely on my desk and I'm using my stamps more often now.
This entire system by TT is well thought out. I have purchased several items from different vendors depending on price but all have proven to be extraordinarily great at organizing what they promise to hold. I have yet to apply the shut your flap closures, haven't found time. ( I bought those from TT website.)
I love storing stickers and embellishments in pages like this because they are easy to find. This page is made specifically for the rack. I ordered the pages without the rack because I wanted to put the pages inside a carrier that I have which is like a huge zippered 3 ring notebook. The pages are just a little too big, but I'm using them in it anyways. The pages are made of a very thin plastic. The top flaps do not fold down over the pocket. Instead they are cut out of the pocket. So things do slide out of them.
