This is an amateurish, impractical, silly, and worthless bit of rip off junk. Save your money and
buy any one of the other ways to force a number with a die. It doesn't matter what you buy, I
guarantee it will be better than this piece of #$%^&. It ought to be illegal and require a prison
sentence for anyone to label something this awful as a 'trick.' However, if you have $25 to throw
away, a use for a magnetic closure packing box, a piece of sponge with a square hole, a die with no
spots, some sticky dots, and crappy inxxxxble thread, go for it. Otherwise, stay far, far away.
