Missionary Magnets ensure your supporters will be reminded to pray for you each time they make a trip to the fridge. Magnets are a perfect addition when sending a thank you note to supporters. We have three sizes that matchup with our missionary prayer card line. Our Small Magnet is the same size (2x3.5) as a business card. The Medium Magnet are our most popular size. Our Large Magnet is the same size (4x6) as a postcard.
