This is one of the genuine Fiedler Dies also known as 10 Seconds Memory Die and measures 1 5/16" in size. I have tested the die for each of its 6 sides and it works perfectly. The original effect is of a smoker from the audience taking the die from the magician who then marks the smoker's cigarette in the middle.

The smoker goes out of sight of the magician and places the die on the table in any position and remembers the number which is on the top. The spectator may also cover the die with a cup. As soon as the cigarette is smoked to the mark the smoker changes the position of the die and gives it to the magician.

The magician then takes the marked cigarette and touches the center of a newspaper and slowly the smoker's number appears burnt into the newspaper! There are many other interesting possibilities to show the audience the number and once you have this amazing piece ideas I am sure will come to mind. Includes 2 pages of instructions. Condition very fine.
