"Pisa" Desk Pen, a design by Adrian Olabuenaga, comes from ACME's collection of Designer Desk Pens. The pen sits in a four sided wooden base, each of the four sided has an engraved plate on it telling the story of the famed Tower of Pisa. The pen sits in the base at the same angle as the actual tower. The pen's design is made by acid etching the details and has an antique silver finish.
