Using this Crayola watercolor set is easy. First, pop out the watercolor chips from the strips and place them in the palette. Then, fill the refillable water brush with water. Press the brush onto a chip to activate the paint and start painting. When you want to change colors, use the sponge in the palette to clean the brush. After using a chip, simply throw it away and put in a new one. Remember, this product is for ages 4 and up. Keep it away from small children who might put the chips in their mouths. To maintain the set, make sure to dry the water brush and palette after use to prevent mold. Also, store the watercolor chip strips in a cool, dry place to keep the colors vibrant.
