To use this body art set, first decide on a design. You can either draw with the metallic pencils directly on your skin or stick the temporary tattoos. For the stick - on rhinestones, peel off the backing and place them carefully on your skin. Make sure your skin is clean and dry before applying any of the items. As for care, avoid rubbing the designs too hard when washing. If using the metallic pencils, keep the caps on tightly to prevent them from drying out. This set is for external use only, so don't ingest any of the products. Have fun and shine bright!
