Using these crayons is super easy! Just start drawing on your paper with the crayons to create bold strokes of color. When you want to add a watercolor effect, dip a paintbrush in water and gently brush it over the crayon marks. You'll see the colors magically transform! If the crayon tip gets short, simply twist the barrel to get more color. Remember, these crayons are water-soluble, so keep them away from water when you're not using them to avoid drying out. They're also washable, but it's best to test on a small area first. These crayons are non-toxic and suitable for kids aged 3 and up, so let your little ones have a blast creating their own masterpieces!
