The Pentel Hi-Polymer Super is a precision mechanical pencil mine designed for consistent, smudge-free writing. Its Hi-Polymer lead formulation delivers a hard, durable line that resists breaking under pressure.
0.3 mm stroke width for fine, detailed lines and precise writing
4H hardness grade ensures a light, non-smudging mark that stays sharp longer
Hi-Polymer lead resists breakage and delivers consistent line quality over extended use
Fits standard mechanical pencil holders for immediate use
What makes the Pentel Hi-Polymer Super different
Unlike standard graphite leads, the Hi-Polymer formulation combines a hard core with a smooth binder, reducing tip breakage and maintaining a consistent line width even under light pressure. The 4H hardness is ideal for technical drawing, drafting, and fine annotation where precision matters.
Ideal for...
Engineers, architects, and students who require a reliable fine-line pencil mine for technical drawings, diagrams, and detailed note-taking. The 0.3 mm stroke suits precision work where standard leads would smudge or wear too quickly.
Application of Pentel Hi-Polymer Super
Insert the mine into a compatible mechanical pencil with a 0.3 mm lead holder
Advance the lead incrementally to avoid pressing too hard on the tip
Use on standard paper, sketch pads, or technical drafting sheets
Store the remaining mines in the original case to prevent tip damage
Pentel is a Japanese manufacturer of writing instruments and office supplies, known for mechanical pencil leads and erasers. The brand has been a staple in the stationery market for decades, offering a wide range of lead grades and pencil systems.
It is a mechanical pencil mine designed for fine, precise writing, technical drawing, and drafting where a hard, smudge-free line is required.
4H is a hard graphite grade that produces a light, thin line. It resists smudging and wears down slowly, making it ideal for detailed work and long drawing sessions.
Yes, the 0.3 mm diameter fits most standard mechanical pencil holders that accept thin lead sizes. Check your pencil's lead capacity before use.
The product is a single mine in a protective case. The case holds the mine securely and prevents tip damage during storage and transport.
Keep the mine in its original case at room temperature, away from direct sunlight and moisture. Avoid storing it in a hot car or damp environment to preserve lead quality.
