These magnets are made right at our facility in Edina! They measure approximately 2.5" on their longest sign and are made of a strong MDF wood. The actual magnets we use are stronger than your average fridge magnet, with the ability to hold about 6 sheets of paper. Each magnet is printed with a super high-quality printing process, and the pictures do not do these justice! We stand behind our quality. If you have any issues at all, we guarantee that we will make it right and ensure your satisfaction.
