The Pentel WOW! Retractable Gel Pen (Model K437C) is a box of 12 medium-point blue gel pens designed for everyday writing tasks. The retractable design features a push-top mechanism to extend the tip and a side button to retract it, keeping the point protected when not in use.

The unique triangular-shaped barrel and latex-free ergonomic grip make the pen comfortable to hold for extended writing sessions while preventing it from rolling off desks and surfaces. The transparent clear/blue barrel lets you monitor remaining ink levels at a glance, and a built-in pocket clip allows easy attachment to pockets, notebooks, and bags.

The smooth-flowing gel-based blue ink writes at a 0.7mm medium point and is permanent, waterproof, fade-proof, and acid-free, making it suitable for professional documents and everyday writing alike. The pens are manufactured with some recycled materials and come with a manufacturer's limited lifetime warranty.
