Pica-Visor Permanent Crayon

The Pica-Visor marking crayon leaves a smudge- and water-resistant mark. Especially useful outdoors, it marks on damp or rough materials, as well as hard, smooth surfaces such as metal or tile, and also works well with puncture-prone materials such as vapor barrier. It has a convenient holster with a toothed clip that grips a belt firmly, making it easy to withdraw the crayon onehanded, and features a tough, oversized plastic housing that is easy to grip, even when wearing work gloves. A simple twist-advance mechanism extends the refillable crayon. Available in white, red and blue. Refills are available separately. Made in Germany.
