These Sakura watercolor pencils give a finish like a watercolor painting when you wet the color with water. One pencil can do both fine, detailed drawing and soft watercolor-like washes. The barrel is made of wood.
Sets come in 12 and 24 colors. Each color is also sold on its own, so you can replace only the colors you use up. The 24-color set includes a brush, a water container, and a sharpener for sketching outdoors.
After coloring, go over the area with a wet brush. The color dissolves, so you can blur it or spread it out.
