Crayola provides superior performance and versatility in a student watercolor. Its semi-moist formula creates bright, vivid colors that mix cleanly without muddying or fading. Pigments stay true and retain richness, from the darkest darks to the palest washes. Classpack includes 24 oval pan sets with size 7 brushes, plus 12 refill strips. Sets and refill strips contain 8 colors: black, blue, brown, green, orange, red, violet and yellow. AP Seal, non-toxic.
