The Tombow KI-MONOGATARI in B and the Mitsubishi 9800 EW B are both recycled pencils that use finger joints from scrap wood to make the pencils, but they are definitely not built the same!
The Made in Vietnam Tombow has a satin finish reminiscent of the Blackwing Natural but with more defined edges on the barrel, modern minimalist branding and feels more substantial.(I actually prefer both of these to the Blackwing Natural) It feels more expensive than it is! The Made in Japan Mitsubishi is unfinished and has a detailed barrel, more of a classic/vintage look, but is easier to sharpen evenly with consistent matching of wood.
The Tombows are ever-so-slightly more prone to flaking on a longpoint sharpener (works fine on a standard one). The Tombow writes smoother on softer/smooth paper (Muji, Moleskine, Midori, Rhodia) The Mitsubishi handles rougher paper better (Fabriano, Leuchtturm, printer paper, pages of a novel/crossword).
Out of the two I slightly prefer the unfinished Mitsubishi as I can use it for a longer time, it feels cheaper but more "organic" if that makes sense. I also love Tombow's attention to detail and prefer its design and consistency of fonts. Seeing as they are recycled, the nitpicky wood and graphite flaking issue may swap places with another batch (it's negated with a standard sharpener). You can't go wrong with either, and as a fan of these recycled matte-finish-sustainable pencils, I'll get both again! (Yes, I am suggesting this course of action)
