Succulent Weatherproof Magnet Magnets are weather-proof, and are strong enough to last on a car. These magnets have a UV-protective coating, which prevents fading in the sun. Each magnet is packaged individually by hand in a clear poly bag. Top of the package is made from folded kraft paper that is punched in the middle, so it can be easily displayed from a hook. Magnet Measures: 2.61" x 3".
