[Easy to adjust the strength of the pen tip] Adds the feel of a brush to the long-selling felt-tip pen. It is colorful and can write it by a writing brush touch smoothly. I can enjoy a writing brush touch for a felt pen sense. The pen tip allows you to easily adjust the strength of the pen, expanding the range of expressions such as illustrations and lettering. Water resistant ink is translucent and excellent for layering [Write thinly] If you relax and write smoothly, you can write thin lines beautifully. [Write thickly] If you press the pen tip with force, you can write thick lines. [Combination] If you write a combination of thick and thin lines, you can create lines with intonation. [Use two colors] If you apply a dark color to a light colored pen tip and then write, you will get a beautiful gradation. [Enjoy the shading] After writing the letters, trace the top half several times to create a gradation of shading. [Fill in] You can easily fill in detailed illustrations.
