■ Well-balanced high performance.
It balances items that are in a contradictory relationship, such as "smoothness," "resistance to breaking," and "resistance to dirt," at a high level. "PentelAin" is smoother than conventional products.
■ Even smoother with a new manufacturing method.
The new manufacturing method uses special oil as a raw material, so the graphite and resin carbonized material crumble smoothly when writing, resulting in a smooth writing feel.
■ Case structure in pursuit of ease of use.
A highly maneuverable case structure completed 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.
■Simple case design.
Coloring based on the lead color (black). If you peel off the sticker after purchase, the design will be unobtrusive and will blend in with your pen case or desk.
