Using these Crayola Neon Light Effects Markers is a breeze. First, pick your paper - they work well on both light and dark, but look extra bright on dark paper. Then, follow the 3 - step layering system described in the instruction guide. Start by sketching your design lightly. Next, use the broad line gel effects neon markers to add color and bring your art to life. You can use the white paint pen for highlights or accents. When you're done creating, cap the markers tightly to prevent them from drying out. Keep them in a cool, dry place. Remember, these markers are safe and non - toxic, but still, keep them away from small children who might put them in their mouths. Enjoy creating beautiful, glowing art with your Crayola markers!
