This is a set of large prisms that measure from the top of the upper prism to the tip just a little bit over 8 inches. The long spear is 7 inches. There are some small chips and flea bites at the tips bubbles on the prisms. They all have tops with wire they're ready to be used. Is there definitely antique prisms you can see by the air bubbles in the craftsmanship.
They are a triangle prism with a octagon, top and bottom.
