Great Organizer!
I bought my first PSB about a year ago, using it to store stickers for the most part until I bought my Cuttlebug machine and started my Cuttlebug die "Collection" LOL! Now I have one PSB full of Cuttlebug dies, sorted by size, type, and theme. The dividers (sold separately) are GREAT so that you can get to the right section quickly. I now have a second PSB to organize all my stencils (I've got quite a collection of those as well!). You can get just about ANY size pocket you like with all the different refills available. Also LOVE that it zips shut, so nothing falls out, ever.
Just an awesome organizer!
