These nail wraps are 100% nail polish and 10-free, meaning they are non-toxic. They require no drying time and can last up to 7 days. You don't need glue or heat to apply them, and they can easily be removed. They are sustainable on natural nails, as well as acrylic, gel, and shellac. Please keep in mind that colors may appear slightly different on screen due to lighting and color resolution. The lasting power of these wraps depends on the application and how much you use your hands.
