Tacticai 12-Pack Green Military Memorandum Book, 3.25” x 5.5” - 144 Pages, for Note and Memo Keeping, Side Bound, Pocket-Sized Paper Pad, NSN 7530-00-222-0078

I carry a pocket notebook at work everyday, all day. I tried all range of notebooks. Some the pages fall out, some the covers get damp and ruin from body heat and sweat. I finally found and have stuck with and they last through their entire use, the covers stay intact, and I can pin a small pin inside the front cover and it withstands that. It is these historically military issue ones. Only thing is they can only be found lined. https://a.co/d/02q5HE9A
