If you really wanna make this ring sizzle as a trick, buy Kenton Knepper's "The Ring". With this
ring, and Kenton's manuscript, you'll have your spectator in a trance before you can say, ummmm. . .
ring.
Kenton's original marketed trick came with two rings, so check on the availability of
those first. Personally, I can't find the set from Kenton anywhere, so this is a nice add-on.
