Rich is much more famous for his spinning metal tops that he and his company create, however, he did a run of BilletSpin Spheres, and they are AWESOME, 16 different metals were used in all! These aren't glass of course, but if you love spheres as much as me, then you'll love having some unique item like these in the collection! (And naturally I have all 16, heh.) They are hard to find at this point, as they're not produced any more and are tucked away in collections, but I'll list them here as I get more or if I release any from my collection.
