IDAKO Gel Pens use a unique gel-based ink. It combines the best of oil-based ballpoint and water-based inks, with pigment suspended in a gel. This thicker gel ink shows up great on dark or slippery surfaces, much better than regular ballpoint or felt tip inks. The pen's fine tip creates neat lines, uses less ink per page, dries quickly, and resists smudging. These pens also last longer than traditional writing tools.

Using this gel pen is easy. Just take the cap off and start writing. It works well on various papers, including those with dark or slick surfaces. When you're done, put the cap back on to prevent the ink from drying out. To keep your pen in good shape, store it at room temperature and avoid dropping it. If the pen seems to be writing less smoothly, try writing a few lines on scrap paper to get the ink flowing again. This pen is designed for long - term use, so with proper care, it'll be your reliable writing companion.
