MONOGRAPH" is sold by Tombo Pencil, well known for its "MONO Eraser. It is a compound mechanical pencil that combines a mechanical pencil, which is shaken to eject the lead, and a holder eraser.

I had been curious about this product on the sales floor for a long time. Last week, I heard that a new color for the 0.5mm lead diameter type was released, so I decided to take this opportunity to try it out.


The new colors are "Silver," "Gunmetal," and "Gold. The elegant metallic colors are rare for mechanical pencils in this price range, and will blend in well with business scenes for both men and women. The price is 350 yen per pen (tax not included), but it has a more luxurious feel than that.

■Lightly shake to eject the lead! Fresnock " function

The "Fresnock" function is used to eject the lead by shaking the pen while holding it in your hand. The see-through tip of the pen reveals the mechanism whereby a pipe-shaped weight moves up and down and knocks the pen.


According to the product information, the force required to shake the pen is only about one-third that of a regular pencil. It is true that the movement of the pipe is light and knocking is easier, but it is not so light as to be surprising.... Incidentally, the clip can also be used to eject the lead, but I was rather surprised at the lightness of the clip.

Furthermore, the clip can be slid upward to prevent the lead from ejecting even if it is shaken. This is convenient because the lead will not pop out when carrying it around.




The eraser on the top of the pen is about 5mm in diameter. It comes out when you rotate the holder, and you can eject about 3 to 4mm. The total length of the eraser is 26mm (16mm for practical use).


The holder is thick enough to make it slightly difficult to see where you are erasing, but it is the perfect size for erasing a single character! The eraser does not deflect when rubbed vertically, so you can erase clearly and neatly. The eraser that comes with the mechanical pencil is so small that it breaks easily, or gets blackened from rubbing, giving it an image of an emergency eraser, but this one is quite reliable.


The writing feel is like a drafting pencil.

The nib has a 4mm long tip pipe, which is an adaptation of a traditional drafting pencil for learning purposes. I usually use a drafting pencil, too, and the stable writing feel and clear view of the nib make it easy to write small letters and create drawings.


However, I personally feel that the grip part is slippery, so it may be hard on my hand if I use it for a long time. The diameter of the pen's shaft is 1 cm, and it is a very cost-effective item for those who are comfortable with this thickness.

Make it look like a pen spinning!

The most notable feature of the pen is the built-in eraser. Since there is no need to carry or change the eraser separately, your writing work is not disturbed much.

The Monograph is truly the "selfish body" (?) of the mechanical pencil world. The monograph is a "selfish body" (?) in the world of mechanical pencils. You can even turn it over and use the eraser in a pen-twirling style to show off your chic side.
