The Spy Sleeve is a Nerf N-Strike product. It is a sleeve that can be attached to one's hand and its intended purpose is for an all-purpose device. It also can double up as a defensive item, along with having seven different functions, as advertised on the box. It comes packaged with the spy sleeve itself, a telescope, a watch, a notepad, a mini-pen and a compass. It is also advertised to be adjustable and can fit most child and teenager-sized hands. Though it is a Nerf product, it was not actually made by Hasbro. It was previously released under other product lines before being inducted into the N-Strike line.
