This is a colored pencil with a two-color gradient. The painter of cartoon creation will encounter such a problem: when selecting color paintings, there are often cases where the color is not enough, and the superposition of single color of colored pencil is blunt and unnatural. This pen looks like a double-headed colored pencil, but it's actually a brush for "harmonizing" colors. All colors are composed of two adjacent colors. When writing with side front, the handwriting is rich in thickness and the color on the stroke will be gradual - the alternating and blending of colors is expressed in such a beautiful way that the writing and creation process becomes pleasant and interesting.

Through different pen-holding methods, the final strokes and colors will be variable and flexible. Different colors will be written at different lengths, so every pen in use is full of expectations. At the same time, the gradation of two colors have more possibilities, blending with each other to meet different picture effects, and there is also a visual "communication" and "interaction" between the stationery and the user.
