Like the bolt action pen mechanism, this Gearshift pen is an ideal gift for any car enthusiast. The mechanism design is based off a five-speed H pattern shifter and can be shifted just like the real thing! The cap features a car tire with a true to life tread and hubcap. The tip features the same tire tread as the cap. The shifter handle includes an etched five-speed pattern. And the industrialized crowbar clip attached to the body with two small screws rounds out the design. Uses a popular Parker style refill.
