Magnetic polishes are an out of this world invention. With the power of a magnet, color is attracted to areas of the nail, and with movement and different viewing angles, shift colors and location on the nail for a futuristic 3D effect.
For best results, you need a strong magnet with the right magnetic pattern, not all magnets will work. The KBShimmer magnet is a strong, flat nail featuring the "cat's eye" or linear pattern, with a gray easy to hold handle and can be used with all magnetic polishes (including gel magnetic polishes). The magnet can also be popped out of the holder to achieve different looks.
