ーーーーーーーーーーーーーーーーーーーーーーーーーーー

A perfectly balanced, high-performance mechanical pencil lead.

Pentel Ain lead achieves an exceptional balance between qualities that are usually difficult to combine — smoothness, break resistance, and smudge resistance — delivering reliable performance at a high level.

Compared to previous models, Pentel Ain provides even smoother writing thanks to its new manufacturing process.

Advanced Manufacturing Process

Using a special oil-infused formula, the graphite and resin compounds break down smoothly during writing. This creates a consistently smooth writing feel with clean, dark lines.

Large Capacity Bottle

• 1000 leads per bottle

• Convenient one-touch open case for easy access

Eco-Friendly Packaging

The Bio Bottle container is made partly from plant-based biomass materials, reducing petroleum-based plastic use while maintaining durability.

Ideal for students, professionals, drafting, and everyday writing.
