Knockle Permanent Marker

Throw away those dry, fuzzy permanent markers in your desk drawer. Pentel Knockle is a superior replacement, with a design that offers longer life and more reliable ink flow. When writing on a porous, absorbent surface like cardboard, other permanent markers dry out quickly. With Knockle, simply press the button on the back and the tip gets an instant ink infusion. That means you can keep marking, labeling, or writing, no matter how big the job.

Pentel Knockle Permanent Marker is available in three colors (black, blue, and red) and two sizes. The Fine size has a 1.2 mm tip, and the Medium size has a 1.8 mm tip. Sold individually. Made in Japan.
