The Cold Steel Pocket Shark Felt Tip Pen is the biggest, baddest, permanent marker around! Superficially, it shares many features common to most markers, but appearances can be deceptive. For starters, it's made from high impact plastic and features walls that are 4 times thicker than similar markers. This means Cold Steel Pocket Shark Felt Tip Markers are built for impact and will survive the meanest blows and roughest treatment imaginable and still function like new. Plus, the screw on cap will stay in place and won't pop off like a regular marker's cap and leak all over your clothes. The Cold Steel Pocket Shark Permanent Marker is easy to carry too. Just clip it to a shirt or coat pocket, or carry in your purse, pack or brief case. Don't spend another day without one!
