Ion Gel Ink

Cross Ion Ink Pens take ion gel pen inks, and as the name suggests, the ink is more like a gel than the liquid in an ink pot. The colored ink pen refills add more of a bold look to your writing. The Cross Ion Pen is a rollerball pen. The gel pen inks aren't as paintlike as India ink or as potentially messy as fountain pen ink pots. The translucent window displays the ion gel refills, so you can see exactly how much ink you have remaining and whether the refill is inserted properly.
