Pentel PENK437A Gel Pen 0.7mm Black Ink Dozen Pack

Product Description

The PENTEL PENK437A is a retractable gel pen designed for professionals and frequent writers who need reliable, lasting ink performance. It uses a 0.7mm tip loaded with black gel ink formulated to be waterproof, fade-proof, and acid-free, making it suitable for documents, field notes, and archival records. The triangular barrel prevents the pen from rolling off surfaces and improves grip control during extended writing sessions. A latex-free grip zone reduces hand fatigue. The transparent barrel lets the user monitor remaining ink without uncapping. Sold in a box of 12 pens per dozen.

The PENK437A fits general office, job-site documentation, and field-service use where durable ink permanence matters. The acid-free ink formula is appropriate for record-keeping that requires long-term legibility. The retractable tip mechanism eliminates cap loss and allows one-handed operation: press the top button to extend the tip and press the side button to retract it. The pen includes a built-in clip for attachment to a shirt pocket, clipboard, or notebook cover.
