My father in law made them for me. He collects logo golf balls and the dimensions are close enough that when he made his displays for the golf balls, it gave me the idea of displaying the chips. The way the are held in is a wooden peg from the hobby shop that has a button like thing on the end. They are all glued in and painted green. I am hoping for more this winter since he has no more room for any more golf ball racks. lol
