Three Merlin?s Coffers. T-171. Tokyo, Japan: Tenyo Co., 1995. A small metal ring is held on a piece of string by a small bead, which obviously is too big for the ring to fit over. They are encased in a small clear box. Obviously, the ring cannot escape from the string, yet just one shake, and that is what happens, and in full view, the ring comes off the string. Lacks original packaging. English instructions. 6 x 8 ??.
