Is that a dinosaur? No it’s a pen. But technically yes it’s still a dinosaur. It’s a dino-pen. Just pull the T-Rex Pen‘s tail off and you can do your writing before the head turns around and bites your hand off. Measures 8″ x 2″ x 3-1/4″. The pen is mightier than the sword, but is the pen mightier than the roar?
