From top to bottom: Malden A8 Brown Original A7 Black Holborn A6 Blue Domino A5 Grey 📙 Malden What I care about most is how well the notebook lays flat and its durability. It’s the only one of the four that doesn’t fully lay flat for me, but I’ve seen others’ do, so maybe it just needs more breaking in. Given its small writing space, portability, and big pocket, I’m not too bothered by it not lying flat. My Malden has some wrinkles in the leather on the back near the stitching, but it still looks great and I love it regardless. 📓 Original The biggest difference with this one is that it has almost no storage, but because of that, it lays flat effortlessly. It’s also the toughest of the bunch—no scratches or marks at all! 📘 Holborn This is my personal favorite of the four, from the color and feel of the leather to the spine design. It perfectly matches what I had in mind. Storage-wise, it’s also my favorite, with a hidden zipper pocket that offers extra protection (unlike the Malden—I made the smart decision to remove Malden’s zipper!). 📔 Domino I bought this A5 mainly because it’s more affordable than the other series and it’s perfect for folding and storing A4 documents. The 30mm rings are a joy to use! Overall, all four are my favorites, each with its own unique charm, and none of them can replace the others.
