It sits below the [MONO R](https://stationerytimes.com/guides/tombow-mono-r-pencil/) and the drafting-grade [MONO](https://stationerytimes.com/guides/tombow-mono-pencil/). We read Tombow's Japanese product page on November 3, 2026. ## Which grade should you buy? **There are eight, from hard 4H to soft 3B.** Most notes and forms are fine with HB or B. | Grade | Model | |---|---| | 4H | MONO-J4H | | 3H | MONO-J3H | | 2H | MONO-J2H | | H | MONO-JH | | HB | MONO-JHB | | B | MONO-JB | | 2B | MONO-J2B | | 3B | MONO-J3B | Each box holds 12 hexagonal pencils of one grade. Tombow's page does not describe the grades, so use the standard H and B scale: higher H numbers are harder and lighter, higher B numbers softer and darker. ## What does it cost compared with its siblings? **The MONO J is the cheapest of the three.** Tombow's list prices with tax for a box of 12 are below. | Pencil | Grades | Box of 12 with tax | |---|---|---| | [MONO J](https://stationerytimes.com/guides/tombow-mono-j-pencil/) | 4H to 3B (8) | 792 yen (about US$5.01) | | [MONO R](https://stationerytimes.com/guides/tombow-mono-r-pencil/) | 2H to 6B (8) | 924 yen (about US$5.85) | | [MONO](https://stationerytimes.com/guides/tombow-mono-pencil/) | 4H to 6B (12) | 1,320 yen (about US$8.35) | The MONO J works out to 66 yen (about US$0.42) a pencil, our arithmetic from the 792 yen price. ## Where does it sit in the MONO series? **It is one of six MONO pencils on Tombow's list.** Tombow's page links the MONO J to the [MONO](https://stationerytimes.com/guides/tombow-mono-pencil/), the [MONO R](https://stationerytimes.com/guides/tombow-mono-r-pencil/), the MONO 100, a mark sheet pencil and a hard-pen writing pencil. Tombow says the first MONO pencil came out in 1963 and the R followed in 1975 to bring the quality to more people. It gives no launch year for the J. All of these share the MONO name, which Tombow ties to the Greek word for unique. ## Which MONO pencil should you pick? **Choose by job, then by price.** - **Notes, forms and school work:** the MONO J, at the lowest price of the three. - **Everyday writing with a recycled-paper box:** the MONO R, which also reaches 6B. - **Drafting and drawing with an eraser in the box:** the [MONO](https://stationerytimes.com/guides/tombow-mono-pencil/), with 12 grades. - **Exam answer sheets:** the [MONO mark sheet pencil](https://stationerytimes.com/guides/tombow-mono-mark-sheet-pencil/), HB only. ## Who is the MONO J for? **It suits people who want a dependable, inexpensive graded pencil for notes, forms and school work.** - **Everyday writing:** Tombow calls it the basic office and study MONO pencil, at 792 yen for 12, about 66 yen (about US$0.42) each. Skip it if you want soft shading grades: the MONO J stops at 3B, while the MONO goes to 6B. For other writing pencils see our [best wooden pencils for writing](https://stationerytimes.com/guides/best-wooden-pencils-for-writing/). ## What should you watch out for? **Use it only for writing.** Tombow's single caution is that the pencil is not for any other use. Tombow's page lists no eraser, so keep a separate one; see our [best Japanese erasers](https://stationerytimes.com/guides/best-japanese-erasers/). ## Where is it made, and what does it cost? **Tombow's page doesn't state a country of manufacture.** At 792 yen with tax for 12 (about US$5.01), a pencil is about US$0.42, in our $ band (under $5 a pencil). ## Frequently asked questions ### What is the MONO J for?
