Using this American Body Art cosmetic glitter is easy. For face and body painting, first clean the area. Then, apply a bit of glue or a sticky base on the spot where you want the glitter. Sprinkle the glitter over the sticky area and gently pat it down. For glitter tattoos, follow the tattoo's application instructions and add the glitter on top. When it comes to craft projects, use glue or an adhesive appropriate for the material you're working with. As for precautions, avoid getting the glitter in your eyes. If it does happen, rinse your eyes with plenty of water right away. Also, don't use it on broken or irritated skin. To keep your glitter in good condition, store it in a cool, dry place and make sure the container is tightly closed. This way, you can enjoy using this glitter for a long time.
