The Simpsons Lisa Spinning Topper Pen

This pen has a spinning Lisa Simpson topper built into the barrel, moved up, down and side to side by turning the dial near the base. Lisa is the family's resident brainbox, a saxophone-playing second-grader with a strong conscience and a habit of being the only sensible voice in a house full of chaos. Her orange hair and pearl necklace make her one of the most recognisable Simpsons characters going.

The dial mechanism means this topper actually spins rather than sitting static, so it holds up to genuine fidgeting at a desk or in class. It suits fans who've always rated Lisa as the smartest member of the family, as well as anyone looking for a fun addition to a pencil case or a shelf of Simpsons collectables. It's a small item, but one with plenty of character packed in.
