Keep a piece of our Prairie Art Exhibit! Leftover paintings have been transformed by local artists into magnet sets, giving the boards new life. Each hexagon is approximately 3/4 inch and has a strong neodymium magnet attached. Set of 4. Photo shows sample – as the magnets are cut from a painting, there will be variations in the set you get. All have 3 plain and 1 etched bee magnet.
