This is a set of 32 magnetic panels, each about 4x6 inches. They have strong magnets inside and hold solidly to your garage door. They give the appearance of a more expensive garage door with glass panels, at a minimal cost. My son in law installed them on his garage door in less than 5 minutes, and it makes quite a difference to the look of the door. You can put them on the door and remove and replace them at any time.
