They say "the pen is mightier than the sword" - and Cold Steel makes some mighty swords, but the Pocket Shark makes for some clever competition. It's the biggest, baddest, permanent marker around! The Pocket Shark is made from a high impact polymer and features walls that are 4 times thicker than conventional markers. This means it's built for impact and will survive the meanest blows and roughest treatment imaginable. Plus, the screw on cap will stay in place and won't pop off like a regular marker and leak all over your clothes. Clip it to a shirt or coat pocket, or carry in your purse, pack or brief case. Theres simply no excuse not to own one!
