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 magnet is strong and features a "cat's eye" or linear pattern. It has a black, easy-to-hold handle, and can be used with all magnetic polishes (including gel varieties). This magnet is even stronger than our gray magnet, and is dual-ended, with a circular magnet at one end for even more fantastic designs!
