This set includes (20) non-toxic and eco-friendly nail wraps, along with a wooden stick and mini nail file. Made with 100% gel polish, it lasts for 14 days without needing a top coat. Simply cure with a UV/LED lamp for 60 seconds - no glue required! These strips are easy to apply and remove, and can be used on natural, acrylic, gel, and shellac nails. Please note that colors may vary on screen due to lighting and resolution, but the lasting power ultimately depends on the skill of the application and how active you are with your hands.
