Using these Crayola Paint Sticks is a breeze. Just remove the cap and start painting on your chosen surface like paper, poster board, or other suitable materials. Since they don't need water, you can paint anywhere without a mess. When you're done, simply put the cap back on to keep the paint stick fresh for next time. As for safety, keep them away from your eyes and mouth. If the paint gets on your skin or clothes, wash it off right away as it's washable. To maintain the quality of the paint sticks, store them in a cool and dry place. This will help them last longer and keep their vibrant colors.
