This unique handcuff key is “hidden in plain sight”, integrated into a pen cap. The cap fits on most any stick type pen. Even when handing the pen to someone, they almost never notice anything out of the ordinary. Or just keep the cap loose in a pocket, no one will pay any attention to it. Completely non-metallic. Just one more option when playing it safe. Color: black. Weight: .07 oz. Patent Pending. Made in Canada.
