The Platinum Preppy fountain pen in Purple is a terrific value for the price! This is a perfect starter fountain pen, or a wonderful option to keep at your desk. The pen features a clear plastic body, and a stainless steel nib that does run a little on the fine side. The Preppy accepts Platinum cartridges or a Platinum converter to use with your choice of bottled ink. It comes with one purple ink cartridge, and the proprietary Platinum converter is sold separately.
