Inka Mobile Pen/Stylus

This compact combination pen/stylus tool clips to a key ring, zipper pull or backpack loop, so it is always conveniently at hand.

Made of carbon fiber and nylon, it is rugged but weighs just 0.35 oz (10g). The pressurized blue ink cartridge allows the pen to write in wet conditions, below-freezing weather or scorching heat, as well as upside down or under water.

Unscrewing the barrel from the caps and turning it end for end exchanges the pen for a stylus tip to use with touchscreen devices. One cap has a stainless-steel pocket clip and a 15/16" S-Biner carabiner that attaches to the clip. When not in use, the small cap can be stored on the end of the large cap.

Measures 4 1/4" long. Refill cartridge available separately.
