With its elegant profile, superb balance, and smooth action, the Manhattan Pen has earned its place as a favorite among pen turners. It's a single twist pen - one turn of the barrel exposes the ballpoint tip. The Manhattan Ballpoint Pen takes standard Parker ballpoint pen refills. Choose from hundreds of eye-catching materials for the barrel. In hardly any time at all, you'll have a twist pen that will truly be turning heads.
