Pilot Nexo Graphite 0.3mm HB Lead Refills 2-Pack

Pilot Nexo Graphite — High-Purity 0.3mm HB Mechanical Pencil Lead, 2-Box Set

Ultra-fine lines demand ultra-reliable lead. The Pilot Nexo Graphite in 0.3mm is engineered for writers, illustrators, and drafters who refuse to sacrifice precision for durability. Pilot's high-purity graphite compound is formulated to be denser and more cohesive than standard leads — which means at 0.3mm, where breakage is the constant enemy, Nexo Graphite holds together under pressure and delivers a consistently dark, clean line from the first stroke to the last.

This listing includes 2 boxes × 25 leads = 50 leads total in 0.3mm HB — a generous supply for technical drawing, exam prep, detailed annotation, or any work where a fine line makes all the difference.

Frequently Asked Questions

Q: How does the 0.3mm Nexo Graphite differ from the 0.5mm version?

A: Both use the same high-purity Nexo Graphite formula. The 0.3mm produces a significantly finer line — ideal for technical illustration, architectural detail, and small handwriting. The trade-off is that 0.3mm leads require a lighter touch; the Nexo formula's high-density construction helps minimize breakage at this size.

Q: Is 0.3mm lead difficult to use without breaking?

A: Thinner leads are inherently more fragile, but Pilot's Nexo Graphite is specifically formulated with a denser graphite compound to improve break resistance at 0.3mm. Writing with a lighter touch and using a pencil with a cushion-point mechanism (like the Pilot S20) further reduces breakage.

Q: What hardness grade is included?

A: This set includes HB grade — the standard hardness offering a balanced combination of line darkness and lead durability, suitable for most writing, note-taking, and general drafting tasks.

Q: Are these leads compatible with my 0.3mm mechanical pencil?

A: Yes. Pilot Nexo Graphite 0.3mm leads are compatible with all standard 0.3mm mechanical pencils, regardless of brand — including Pilot, Uni, Pentel, Staedtler, OHTO, and others.

Q: How many leads are included in total?

A: This is a 2-box set. Each box contains 25 leads, for a total of 50 leads.

Q: Are these suitable for use on exam answer sheets?

A: Yes. The HB grade produces a clean, dark line that is reliably detected by optical mark recognition (OMR) scanners used in standardized testing — making these leads a solid choice for exams.
