This product is comprised of eco-friendly and non-toxic materials, and includes 32 pieces, a wooden stick, and a mini nail file. It is made of 100% gel polish and can last up to 14 days without the need for a topcoat. To cure the polish, a UV/LED lamp is required for 60-120 seconds. There is no need for glue and removal is easy. These pedicure strips can be applied and removed with ease on natural nails, acrylic, gel, and shellac. Please note that colors may vary slightly on screen due to lighting and resolution, but the lasting power of these strips is dependent on proper application and how much wear and tear they receive on your feet.
