Problemo Dice (Germany)......$32.00

Here's a really wonderful close-up dice trick you're going to love
doing whenever you get the chance!

Six dice in a small box are shown.  The tops of all the dice show a
different number from one through six.  The cover to the box is
replaced.  Now a small cup and a single die are shown and anyone
shakes the cup and then dumps the die onto the table.  Whatever the
top number of the die shows, when the cover to the box is removed,
all the six dice in the box now show the same number!

All six dice and the box can be examined.  Totally mechanical.  No
sleight of hand required.
