Chunkies are super easy to use, clean and portable because they're like painting with a crayon. Just uncap, twist and start painting. Chunkies comes in a set of 6 different colored paint sticks each in a thick barreled casing so they're easy for little hands to hold. The paint colors are quick drying and won't smudge, but it's easy to mix colors to make even more colors. It's magic! Care and use recommendations: Keep capped when not in use, to help prevent drying. Cover and protect your workspace. This product may stain some surfaces.
