Our 6x4 oval pickleball magnets are made and inspected in the USA. Printed on premium 36mil ultraflex magnetic vinyl decal material. UV coated for weather-resistance and non-fade graphics. The durable finish will not crack nor peel. These magnets are perfect for indoor or outdoor use. Our pickleball magnets are easy to apply, durable and reusable. These magnets are 100% guaranteed to stick to all ferromagnetic materials including iron, cobalt, nickel, and steel. For example our pickleball magnetic decals can be use on cars and trucks, campers and RVs, motorcycles, school and work lockers, whiteboards, washers and dryers, refrigerators and dishwashers, filing cabinets, toolboxes, garage doors, and on just about any other ferromagnetic metal surface. While designed to last for years, magnetic decals do not adhere to surfaces permanently like adhesive stickers do. This allows you to reposition your magnets to protect the metal surface from uneven fade. Magnetic decals are reusable, which sets them apart from adhesive stickers. Our magnets come with application, proper care, and maintenance instructions. Proper use and care will extend the life of your magnet and protect the metallic surface to which it is applied. This 3 Pack Pickleball Car Magnets includes A-to-Z guarantee which covers both the timely delivery and the condition of your items.
