Frequently Asked Questions

Q: Which hardness should I choose — HB, B, or 2B?

A: It depends on your use case. HB is the safest all-rounder for everyday writing, exams, and note-taking. B is slightly softer with a darker line — great for journaling and smooth writing. 2B is the softest and darkest of the three — ideal for drawing, shading, filling in bubble answer sheets, or writers with a light touch who want a bold line.

Q: Are these leads compatible with my mechanical pencil?

A: These are standard 0.5mm diameter leads, compatible with virtually all mechanical pencils that accept 0.5mm refills — including ZEBRA, Pentel, Pilot, Uni, Staedtler, and of course KOKUYO pencils. Check that your pencil is rated for 0.5mm before purchasing.

Q: How many leads are in the full set?

A: The set includes 5 tubes × 30 leads = 150 leads total. Each lead is 60mm long, giving you a substantial supply for extended use.

Q: Do KOKUYO Campus leads break easily?

A: KOKUYO Campus leads are formulated for reduced breakage compared to generic alternatives. That said, all 0.5mm leads can snap under heavy pressure or if dropped. Writing with a moderate, consistent pressure will maximize lead life.

Q: Can I use these leads for drawing and sketching?

A: Yes. B and 2B grades are particularly well-suited for sketching, shading, and illustration work with a mechanical pencil. HB works for technical drawing and fine linework where precision matters more than darkness.

Q: Do the leads erase cleanly?

A: Yes. KOKUYO Campus leads erase cleanly with standard erasers (rubber, plastic, or kneaded). 2B leads may leave slightly more residue than HB due to their softer composition, but overall erasability is good across all three grades.

Q: Is this an authentic KOKUYO product?

A: Yes. These are genuine KOKUYO Campus series lead refills from Japan.
