STEIN is Pentel’s latest pencil lead technology which stands for "Strongest Technology by Enhanced SiO2 Integrated Network". The reinforced silica inside forms a honeycomb-shaped structure, achieving the highest level of strength.
The lead is also smear resistant. It is excellent in attaching graphite to the paper surface, making it highly resistant to abrasion stains. Ideal for left-handed users.
- 10% stronger than existing Pentel leads, thanks to a honeycomb structure.
- Smoother than traditional refill leads on the market.
- High smear resistance which avoids smudging hands during writing or drawing.
