One tool does both jobs. Every pencil in this set of 12 is a watercolor pencil at one end and a real paintbrush at the other, joined by a gold ferrule, so you sketch and color with the lead, then flip the pencil over, dip the brush in water and the drawing turns into a watercolor painting.

The 12 are rainbow colors plus skintones, which is the part most cheap sets leave out, and the leads are blendable rather than waxy. Snifty calls them 12 vibrant, artist quality colors for painting and drawing, and the brush tip is color-matched to its own pencil so you are never hunting for the right one.

Nothing else to buy and nothing to set up: no separate brushes, no palette, no water pot beyond whatever cup is nearby. It travels well, which is why it suits a sketchbook bag as much as a kitchen table. Non-toxic and conforms to ASTM D-4236.
