Pentel PENK437C Retractable Gel Pen 0.7mm Blue-black 12pk

Product Description

The PENTEL PENK437C is a retractable gel pen designed for professionals and everyday users who need reliable, permanent ink performance. It uses a 0.7 mm tip and delivers blue-black ink that is waterproof, fade-proof, and acid-free, making it suitable for documents and records that must hold up over time. The triangular barrel promotes a stable, controlled grip and prevents the pen from rolling off surfaces. The transparent barrel allows users to monitor remaining ink at a glance. This unit is sold as a dozen of 12 pens per package.

The PENK437C is suited for office environments, field documentation, and any application where ink permanence matters. The latex-free grip makes it appropriate for users with latex sensitivities. The pen advances the tip with a push-top button and retracts it with a side button, keeping the tip protected when not in use. A built-in clip allows attachment to shirt pockets, notebooks, or clipboards, making it practical for technicians and professionals who carry tools and paperwork in the field.
