Never run out mid-stroke again. The Tombow MONO Graph Lead Refills are engineered to match the precision and smoothness of the MONO Graph mechanical pencil series — but they work beautifully in any standard 0.5mm mechanical pencil. Each box contains 40 leads at 60mm length, and this set gives you two full boxes so you’re always stocked.

📝 HB vs 2B — Which Grade Is Right for You?

• HB: The universal standard. Firm enough to write cleanly without smudging, dark enough to read clearly. Best for everyday note-taking, exams, and general writing.
• 2B: Softer and darker. Glides across paper with minimal pressure, producing rich, expressive lines. Best for sketching, shading, manga, and fine art.

🔬 MONO Graph Lead Formula

Tombow’s MONO Graph leads use a refined polymer core that balances smoothness and break resistance. The result is a lead that writes consistently from the first stroke to the last — no scratching, no unexpected snaps, no uneven darkness. Whether you’re filling in answer sheets or rendering fine details, the lead performs reliably under pressure.

❓ Frequently Asked Questions

Q: Are these genuine Tombow leads from Japan?

A: Yes. These are authentic Tombow MONO Graph lead refills, sourced directly from Japan. Tombow has been producing precision stationery since 1913 and is one of Japan’s most trusted brands.

Q: Will these leads work in non-Tombow mechanical pencils?

A: Yes. These are standard 0.5mm diameter leads and are compatible with virtually all 0.5mm mechanical pencils from any brand — including Pentel, Pilot, Staedtler, Zebra, and others.

Q: What is the difference between HB and 2B?

A: HB is a medium-grade lead — firm, clean, and ideal for writing, exams, and everyday use. 2B is a softer grade that produces darker, smoother lines with less pressure — preferred by artists, illustrators, and anyone who sketches or shades.

Q: How many leads are included in total?

A: This set includes 2 boxes × 40 leads = 80 leads total, all in your selected grade (HB or 2B). Additional bonus leads are also included.

Q: How long is each lead piece?

A: Each lead is 60mm in length, which is the standard length for most mechanical pencil lead tubes and provides a good amount of usable lead per piece.

Q: Are these leads break-resistant?

A: Tombow MONO Graph leads use a polymer-reinforced formula designed to resist breakage during normal writing and drawing. While no 0.5mm lead is unbreakable, these perform well under typical pressure.

Q: Can I mix HB and 2B in one order?

A: Each set is sold in a single grade (either HB or 2B). To get both grades, simply add one of each to your cart.
