Welcome to fine writing, with a twist. The Sheaffer® Prelude® MPI (Multi-Purpose Instrument) is part innovation, part fun, part gadget and all cool. It converts easily from a ballpoint to a highlighter with one simple rotation. The Prelude® MPI is the pefect companion for the busy professional or the person on the go. And when you go, we want you to go in style. Working on documents on trains or buses, in offices or airports, has never been so easy. Or fun. One moment, it's a ballpoint. The next, it's a highlighter. Think of it as Superman in your attaché. Without the cape, of course.
