The pens have nylon brush tips. To create color gradations, touch brush tips of different colors together. To blur or lighten colors, touch the brush tips to water before drawing. The ink is dye-based, and you can adjust ink flow by squeezing the ink cartridge. Ink refills are available.
The ink is dye-based and water-soluble. The ink is not light-fast.
Note: If you are unable to twist the cartridge off from the brush part (clear barrel) of the pen, try twisting in the opposite direction.
If the tip becomes dry or cracked, submerge the tip (but not the rest of the pen) in hot water for 1–2 minutes.
