It’s not often that I find an entire line of products that I’ve never actually used. Sure, there are things out there I’ve never reviewed, but the Tombow Mono Graph mechanical pencil was so new to me that for a brief minute I couldn’t initially figure out how the “shaker” lead advancement and “lead lock” mechanisms worked. Fortunately, it’s not complex at all, and this little pencil has turned out to be a fantastic discovery.
This simple, contoured plastic section is quite comfortable to use. You can see the metal shaker mechanism just above the grip.
Tombow is a Japanese stationery company whose excellent office-style products can be overlooked, especially here in the U.S. where the company is often better known for art supplies such as colored pencils. I previously reviewed the (also excellent) Zoom L104 Multi Pen - a slim 2+1 ballpoint/mechanical pencil that impressed me. I came away from that review intending to dive a bit deeper into the Tombow lineup, but there are only so many hours in the day that it’s taken me a few years!
When I received a huge box of select Japanese mechanical pencils from one of my distributors a couple of weeks ago, these pastel-colored Mono Graph pencils caught my eye. Tombow typically nails the price-value proposition, and at less than $8, these pencils intrigued me. I also noticed the “Shaker” description - what does that mean? Pretty much exactly what you would think.
For any Tombow mechanical pencil that uses the descriptor “shaker”, you can advance the lead by, well, giving the pencil a shake. The barrel contains a sliding weight inside that trips the mechanism and advances more graphite. This comes in handy when you’re writing. As you find yourself wearing down the point of the pencil, simply flick your wrist to extend the lead. This can be a lot more convenient than changing your grip to click a physical button mid-sentence. You can slide the clip up to activate a “lead lock” mechanism, which prevents you from accidentally “shaking” too much lead out of the pencil. Of course, you can also press down on the clip to extend the lead like a traditional knock.
The clip slides up and down to either lock the shaker mechanism in place, or to work like a traditional knock and manually advance the lead.
The second thing I love about Tombow mechanical pencils are their integrated erasers. Tombow’s white “Mono” erasers are among my favorite on the market - they last a long time, erase cleanly, and don’t leave much, if any, residue on the page. The Mono Graph mechanical pencil features this same eraser, which extends from the end of the pencil using a twist mechanism.
The Mono eraser - a longtime favorite!
Takeaways and Where to Buy
As I always say, the stationery world is so broad and wide-ranging that it never gets boring. You can always find new rabbit-holes to dive into, and lately for me that’s included mechanical pencils. The Tombow Mono Graph pencils are inexpensive, comfortable to use, and feature one of the best erasers on the market. As someone who uses their mechanical pencils for writing and notetaking, as opposed to art or technical work, I’m sold on Tombow’s “Shaker” mechanism as much more than a gimmick.
The Shaker mechanical pencil comes in a range of fun colors, including the five pastel options shown here. The one I’m reviewing is the Mint (far right), and the pastel blue is ever-so-slightly lighter though it’s difficult to see in most photos.
The Tombow Mono Graph Shaker mechanical pencil is priced at $7.59 for either the standard black/blue/tricolor models or the pastel version, making it an attractive value proposition. All pencils take .5mm-sized leads. The T.G.S. Curated Shop now carries a selection of Tombow mechanical and woodcase pencils, including the Mono Graphs, as well as Tombow erasers and select pens! We’ve significantly expanded our pencil selection in recent months, and just received a large restock on most brands, so please be sure to check it out.
