Pentel has redefined the chemistry of the pencil refill with the all-new Pentel Ain (C28x series). Developed to surpass the high standards of the previous "Ain Stein" line, this new series achieves a superior balance of durability and smoothness. By reinventing the internal ceramic frame that supports the graphite, Pentel has created a lead that glides across paper with noticeably less resistance while leaving a crisp, dense mark.
This is the ultimate performance upgrade for your writing toolkit. The new formula is formulated to adhere firmly to paper fibers, drastically reducing smearing and keeping your drawings, hands, and notes pristine even during intensive sessions.
Advanced Engineering & Ergonomics:
While engineered by Pentel, these leads are designed to maximize the performance of any professional mechanical pencil. Whether you are using a Kaweco, Staedtler, Rotring, Uni, Zebra, or Tombow, loading them with Pentel Ain ensures you experience the absolute pinnacle of Japanese lead technology. It is not just a refill; it is a precision component for your finest writing instruments.
