Two Permanent Ink Pens in One.

The Doubleheader® Permanent Ink pen combines the flexibility of the two-sided Doubleheader pen with the all-purpose utility of permanent ink. On one side, there's a bullet tip marker for all your labeling needs. On the other, a finepoint pen for desktop writing. Both sides feature water and fade resistant permanent black ink that can write on most any surface: film, plastic, glass, wood and metal. Quick drying ink to help prevent smears.
