Kuretake ZIG Clean Colour Dot - Metallic Blue - Water-based pigment ink, so colours do not bleed even when you layer other colours. (*) * It will be slightly different depending on the drying condition of the ink and the type of the paper. You can draw cute illustrations by drawing dots or droplet shapes with a dot pen tip and adding the patterns with the fine tip side. If you press the entire head of the dot tip onto the paper, you can draw larger dots. If you apply soft pressure to the dot pen tip, you can draw small dots. You can draw droplet shapes by pressing down firmly onto the paper, then simultaneously moving the pen tip while releasing pressure.
