I have no idea why, but Japanese office/stationery products are infinitely better than their North American counterparts. The difference in quality is just palpable – they're visually appealing, built to last, and thoughtfully designed. I prefer spiral notebooks to anything with a binding, and this particular one by Maruman quickly became my favorite. It's large without being cumbersome, and elegant enough to fit into a professional setting. The paper is creamy and smooth, and even my extremely fine tipped pens glide along like a dream, without a hint of scratchy resistance. I'm also a big fan of the page layout. The subtle gray lines keep your handwriting tidy, but they're virtually unnoticeable when you're scanning over a full page of notes. That's the kind of useful, simple design tweak that makes you go, "wait, why isn't the standard way to make this thing?"
If you're trying to choose between similar notebooks, I highly recommend this one. I've had mine for a few months, and I'm investing in several more.
