Joycolor pen / educational kids pen

Joycolor pen

What color would you expect to come out? Guess what?
Children are interested in drawing pictures using various colors. However, they do not understand about the concept of color mixing and its result. Joycolor Pen is an educational tool, which visualizes the result of mixed colors that kids chose by the action of pushing buttons.
You can try different sets of colors as well as red, blue, and yellow mixing. You can also adjust color density pushing buttons.
