Tombow OnBook mechanical pencil is the perfect companion to a paper planner or Moleskine-type notebook. The pen is flat on one side to fit snugly against the spine of your book. The metal clip is solid and is very thin making it easy to slide along the spine of your notebook. It accepts any 0.5mm lead and is available in a half a dozen colors from JetPens. Under the cap is a tiny eraser which is not great but just enough if you’re in a pinch.
“I love the idea of really well-designed, well-made, preferable simple, American-made (or Canadian-made) products, particularly if they have really smartly-designed websites that are entertaining to read. So here’s your product placement for this evening: Field Notes. Has a kind of American Muji thing going on, it seems to me.”—A little shout-out to Field Notes from one of my favorite authors, William Gibson.
