PERMANENT NAIL POLISH Permanent nail polish is an application that saves you from the problems of non-extendable, broken and/or deteriorated nail polish. It is a nail polish application that preserves the permanence of the nails for a long time without any deformation. With permanent nail polish, the nails do not come off or deteriorate for a very long time, and the nails look smoother, smoother, brighter and well-groomed.
