SUN-STAR Two Color Line Pen Twiink,B Set, Different 4 Colors Pattern Set, Water-Based Paint Pen, (Pink x Light Blue, Violet x Pink, Light Blue x Orange, Pink x Green)
Two colors in one pen that can be used in three different ways, a single-color, or two colors, depending on the angle and direction you hold the pen. The ability to draw two colors at the same time eliminates the inconvenience of having to draw twice or prepare two pens when drawing double lines or illustrations with multiple colors.
Decorating a message card, notebook, or diary, simply drawing a line (solid line, dotted line, wavy line, etc.) with two colors can make them stand out, so it is recommended even for those who are not good at drawing illustrations.
It is also convenient to use as a "marking" to make important points stand out when summarizing notes or writing in text. Lines, arrows, circles, balloons, etc., which are often used when summarizing, can be made easier to see at a glance without much effort by using different colors and two-color lines. You can also use two colors in one pen, reducing the number of pens you need to carry around in your pen case.
