Prison inmates are a pretty deprived lot, and they would do virtually anything to escape. This includes using everyday items as weapons, and you would be surprised to know how a pen can be turned into a lethal weapon when used in the right hands. The Prison Pen offers a new twist to the equation, since it is made from a soft rubber material that bends under the slightest of pressure. Prison guards and wardens can now breathe a sigh of relief, since the Prison Pen remains effective as a writing instrument and nothing else. Spycatcher is carrying the Prison Pen for $10.
