Smooth watercolor gel crayons (Cream pas)

In South Korea, gel crayons are commonly used for children because they can easily draw lines with little pressure and color large areas comfortably. Additionally, Dong-A Toru's gel crayons have the advantage of smooth application, vivid colors, and no crumbles.

However, they are not washable, so I would like to recommend for children over four years old, while washable window gel crayons are recommended for younger children.
