These are 3" round interchangeable discs that change in the 18 inch "Welcome to our Home" sign, Changeable Gnomes, or Hanging Post Sign. Each one comes with a steel plate on the back to hold in in place with the sign's magnet back. You can order these finished or as a fun DIY project. Finished rounds will be similar, not exact match, to sample pictures.
