Using this nail foil set is easy. First, get your nails ready. Push back the cuticles and make sure there's no oil on your nails. You can use professional nail products to do this. Apply a base coat and wait for it to dry. Then, put on dark nail polish. It's better to do it twice, waiting for the polish to dry a bit between coats. It should be soft when you press on it. Cut a piece of foil that's just the right size for your nail. Press the shiny side of the foil onto your nail and rub it with your finger or a rubber hoof stick. You can mix different colors of foils on one nail to make it look really cool. After that, take off the foil, and the pattern should stick to your nail. If there are some parts missing, put on top - coat on those areas and repeat the pressing step. Once everything is dry, add a protective coat to keep your nail art looking good. Remember to keep the set in a dry place when you're not using it. And be gentle when applying the foils to avoid any tearing.
