These are called the 3-in-1 because they can act as 1) a wax crayon, 2) a colored pencil, and 3) watercolor -- all in one! Which makes them a super versatile tool for kids (and still a pile of fun for adults to play with and use as well).
Just draw away with the tool on paper, and then come back in later with a wet brush to activate and move around the pigment to create a more blended, painterly look. The body itself is short and chunky, too, making it easy for kiddies to grip.
