uni Vision Stick Roller Ball Pens, 0.7 mm Fine Tip, Black, Pack of 36

The Rollerball pen has free flowing and fluid ink, similar to a fountain pen. You can actually feel the ball contacting the paper and see the ink flowing out of the pen as you write. Each roller pen features waterproof uni Super Ink which protects against water, fading, and fraud. Archival quality and acid free ink is great for documenting and record keeping. The larger particles deliver solid vivid colors every time you write.
