Magnetic polishes are an out-of-this-world invention! With the power of a magnet, color is shifted and relocated on the nail for a futuristic 3D effect. For best results, you need a strong magnet with the right magnetic pattern – and not all magnets will work. The KBShimmer Black S Magnet is strong and features two ends, one with a “cat’s eye” or linear pattern and the other that when used on its side, produces a X pattern. The KBShimmer Black S Magnet can be used with all magnetic polishes (including gel varieties).
