I loved that these came in a set of three. I designated one for work, one for personal use, and one as backup. I carry it around in the Moleskine A4 folio and love that I can always have it with me to jot down any thoughts or notes without adding significant weight to my shoulder tote. It has a signature folder flap in the back, a feature I have come to love using Moleskine notebooks for a while. Despite the covers being made of paper, they are surprising durable and have withstood significant wear and tear from many journeys on planes and trains; even having gotten a bit wet at one point. They lay flat but can be folded like one would a spiral bound. I like that the back pages are tear-out although I didn't realize those until I neared the end of one of them. The pages tear out easily enough if needed so I'm not sure this is necessary; I might suggest that either all or none of the pages have this perforation. At any rate, they don't interfere with the user experience. I purchased the graph paper notebooks but they also have lined. (I find graph paper notebooks harder to find but seek them out because my handwriting and thought organization somehow improve.)
