Made of polystyrene with a thick, highly adaptable body, it quickly gives your nails a shiny, healthy look in just 6 strokes! One side smooths away minor ridges on the nail surface, while the other smooths and provides a spectacular shine. Step 1 is used to remove roughness and smooth the nails, gently and gently rubbing it over the surface of the nails. Its best to do this every two weeks. If your nails are very thin or weak, its best to do this step every three weeks. Step 2 provides an extraordinary shine in just six coats, so theres no need to use polish. Once a week is enough for your nails to shine spectacularly. And if you like painting your nails, remember to give them a break: at least a couple of days between polish applications. This will prevent them from drying out, weakening, or yellowing.
