STEIN is Pentel's latest pencil lead technology. It 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 at attaching graphite to the paper surface, making it highly resistant to abrasion stains. It is ideal for left-handed users.
Features:
- 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.
- It is supplied in a convenient swivel-top container made from 90% recycled material.
- In every container, there are 15 pieces of 0.3mm lead, 40 pieces of 0.5mm or 0.7mm lead.
