WOW! Retractable Gel Pen

The Pentel K437C WOW! is a retractable gel pen with blue ink and a medium tip. Its triangular barrel and latex-free grip provide comfort and prevent the pen from rolling off flat surfaces. The ink is permanent, waterproof, fade-proof and acid-free for durable writing. A click mechanism advances the tip while a side button retracts it.

Ideal users and limits

Suits professionals and students who want a comfortable, non-rolling pen for everyday writing and archival documents. Not suited for users who prefer fine or broad line widths, or those needing ink colours other than blue.

Medium point size

The medium tip produces a standard line width for general handwriting and note-taking. This point size determines whether the pen matches the user's preferred stroke thickness.

Questions about this item

Should I buy the dozen pack or look for single pens?

The listing describes a dozen retractable gel pens, so you receive twelve blue medium-point pens in one box.

How does the medium tip perform on everyday paper?

The medium point lays down a smooth blue gel line that is permanent, waterproof, fade-proof and acid-free on standard office paper.

Does the click mechanism advance and retract reliably?

Clicking the top extends the tip and pressing the side button retracts it, giving a positive action each time.
