These rad magnets are just over 1.25″ across, and made of molded concrete, with heavy duty ceramic magnets epoxied on the back.
Made from my concrete brick mix leftovers, I eliminate nearly all of my waste that would otherwise end up in the landfill.
Overall about .75″ deep. Mixed colors, finishes and textures.
Because no two magnets turn out alike, these are only sold in random sets of 4.
