High-quality fountain pens priced as disposable pens? Yes, it's possible with Pilot's amazing Petit1 Mini fountain pen series. They are versatile, compact, portable, and come in a stunning number of colors (9 colors to choose from). The ink is water-based and smudge-free.
The Petit1 has a unique see-through ink feed under the nib, so the ink color is visible which is a nice visual touch. When you pop the ink cartridge in, you can watch the ink creep its way up the small wick inside the feed, and the color spreads to the outer edges of the feed.
