A twin-type water-based color pen that allows you to push Dots and draw lines. The soft-colored round stamp core (0.5mm in diameter) Can easily draw Dots, and can draw various lines using edges as well as extremely thick lines. With a clear bright color ultra-fine core (0.3mm), you can draw smooth lines. Since the color is a little darker than the stamp core, even if combined with dots, It will produce a sharp and beautiful color. Usage is infinite depending on the idea. You can create cute illustrations and icons By using only a round stamp or combining extra fine lines.
