Genuine & sustainable, this set includes (16) pieces along with (1) wooden stick & (1) mini nail file, all made of 100% gel polish to ensure lasting results for 14 days or more without the need for a topcoat. Simply use a UV/LED lamp to cure for 60-120 seconds and say goodbye to tedious glue application and removal. Suitable for natural nails, acrylic, gel nails, and shellac, these strips are sure to impress with their vibrant colors (please note that colors may appear slightly different on screen due to lighting and resolution). The lasting power of these strips also depends on your meticulous application and how you treat your hands.
