This set is environmentally friendly and contains 20 pieces, along with a wooden stick and mini nail file. Created with 100% gel polish, it can last up to 14 days without the need for a topcoat. Simply use a UV/LED lamp for 60-120 seconds to cure and you won't need any glue. It's easily applied and removed, making it a great choice for natural nails, acrylic, gel nails, and shellac. Keep in mind that screen colors may vary due to lighting and resolution, and the longevity of the nail strips depends on your application and how gentle you are on your hands.
