It is made from the glass-reinforced plastic, Grivory, and features walls that are 4 times thicker than similar markers. This means it's built for impact and, in a self-defense emergency it can become an efficient Yawara stick for driving off an attacker. Plus, the screw-top cap will stay in place and won't pop off like a regular marker's cap would when you strike a percussion blow, or when obtaining joint locks or submission holds.
It's 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!
