Lot of 36 Vintage Aurora AFX Motor Magnets HO Slot Car Red Blue White Green Black. I am no slot car expert and don't know much about these. This lot was an estate sale purchase. What you see in the photos is what you will receive. 4 of the magnets are thicker than the other 32. The 4 thicker ones are the top 2 in each stack, as seen in the photos. Thanks for looking!
