CRAFT MAGNETS: Ever thought about making your own fridge magnets? Our material is good for arts and crafts, photos, drawings and postcards, yet still strong enough to support all shapes and sizes of metal dies. And the thicker sheets are ideal for holding up office items to magnetic whiteboards, the refrigerator or filing cabinets. Get creative and organized at the same time! SIGN MAKING: These magnets are an excellent choice for making car signs, among many other crafting, DIY and household purposes. Yes of course, you could use these sheets to make a magnet sign for your car, van, truck or trailer… but they can be also used for so much more than that! HIGHWAY GRADE: Sticks great to most metal surfaces! The 30mil material is strong enough for making magnetic vehicle signage and its powerful grip means that it won't fall off your vehicle at highway speeds. SIMPLE TO USE: Self-adhesive backing gives you the option to use your magnets the way you like. The adhesive allows for an efficient application and an effective bond. It really sticks! (please note we strongly suggest allowing the adhesive to cure for 24 hours once applied; this will create the strongest bond possible). EASY TO CUT: Very flexible and easily cut with scissors, sharp craft knife, hole punch or paper cutter - simply awesome for making your own magnets at home (please be safe!). Please note that the thicker materials will require more force.
