This is a pen. A fun item for one-liner gags at year-end parties and other events! Regular price: 19,800 yen Purchased as an outlet item and stored at home. No instructions are included. It seems to be a joke item where you hold a "finger pen" between your fingers and perform a trick as if you're pulling your finger off with your other hand, then shout "This is a pen!" #Joke #Gag #Pen #Finger
