Being offered is what I believe is new old stock 10 sided lightning ball. I believe that would make it a decagon. It is marked D and S. With patent pending. You can see it has the couplings on the top and bottom. I do not see any chips, cracks, brakes, or repairs. It will come in what I believe is the original sleeve, which is very dirty and dilapidated. I am also listing a very cool lightly swirl blue round ball in 1 other auctions. And 2 white round balls. I would combine shipping for just an additional two dollars each after your first purchase.
