However, within about two months the binding had completely split and the back cover fell off with very gentle, normal use

Best use for the pocket/puch though is to use to retain small size papers, receipts, and business cards to have then handy, but not falling out or sliding around

I also have the Tom Bihn Field Journal Notebook which uses the same size paper and accessories, so I am making good use of the many dividers, pockets, and protectors that I bought

I really enjoy using notecards to get down ideas, but the most commonly used 3x5 size are way too small for me.
