This is a thin-line (TL) magnet ideal for sending with White Rock Beach greeting cards as it is lighter and more durable for mailing. You might be able to include it with a greeting card without extra postage. Please verify weight before mailing at your local post office. These Lucky Magnets can be used as a Lottery Charm® Lucky Magnet to hold your potential winning lottery ticket to a fridge or other magnetic surface. As seen on @goVanTVShow
