The Parker Jotter is the Parker Pen Company's second and best-selling retracting refillable ballpoint pen. A number of Jotter barrels have a marbleized appearance. Whatever the case, it is rare, expensive and eagerly sought after by Jotter collectors. He has also served on the Boards of Jotter Technologies and Office Depot. Black and white versions of the large diameter Jotter have also been found. The so-called "girl's" Jotter was a smaller version of the original.
