Jerrzi Ruyi Magnetic

Jerrzi Magnets! And in the style of their other circular dustproof stuff like Posiedons. Does that make them better? Not sure about the shape's effectiveness but they do use POM housings and an LY stem which is cool. I wonder if LY floats good enough to hold up the magnet? Haven't tried it yet.
