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.
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.
- Supplied in a convenient swivel-top container which is made from 90% recycled material.
- Each container contains 40 pieces of lead.
