6-sided dice that bear a strange combination of numbers, but still have exactly the same odds for every total as an ordinary pair of d6s. See http://en.wikipedia.org/wiki/Sicherman_dice
They have an empty pocket inside, full of support material, to lower price.
(general advice: dice look good in detail material)
