Pentel Mechanical pencil lead Pentel Ain

It achieves a high level of balance between seemingly contradictory characteristics such as smoothness, resistance to breaking, and stain resistance.
"Pentel Ain" is smoother than previous models.
Thanks to a new manufacturing process that uses a special oil as a raw material, the graphite and resin carbide crumble smoothly when writing, resulting in a smooth writing experience.
A highly operable case structure perfected through repeated surveys and behavioral observations.
You can operate it with one hand while keeping the case facing up, reducing the risk of spilling the lead.
Coloring based on the core color (black).
Once you have purchased it, you can peel off the sticker and it will have a subtle design that will blend in with your pencil case or desk.
The lineup includes lead sizes that are compatible with all Pentel mechanical pencils, from ultra-fine to thick leads.
*There are no blue core polyseal specifications.
