Description This is the ultimate bug crusher and yes, that’s a normal size pinball right in front of it. Four inches of the same high quality steel as the Ninja ball, this monster will get them talking. Use as a trophy for your pinball league or tournament. Suitable for display and you can get an optional oak stand for it to nest on ( and not roll away)! This polished sphere comes in at a whopping 9 pounds, 7 ounces – more than half the weight of a bowling ball! 4 inch diameter AISI 52100 Chrome Steel.
