This is a vintage Kurt S. Adler 10 piece golf light set in its original box, sold by Dillard's Department Store in the 1970's.
The set features 5 ea. 4" plastic golf bags and 1 1/2" golf balls that snap over most mini lights allowing you to use it as a single string set or place the caps wherever you wish over mini lights on your Christmas tree as you choose.
If you are a fan of this wonderful sport as my late, great father-in-law was who got a kick out of placing these on his tree every year!
I have only 3 sets so don't miss out!
