This is a pair of two non matching numbered dice from the Harrah's Casino in Las Vegas NV. These are used, canceled dice and were part of a collection. This is a set of two dice that are white  with two different non-matching numbers. (DICE 6)  *From Abbie: Due to COVID, the casinos are throwing away the used dice and cards.  Gift shops in the casinos don't them and pit bosses are not giving them away. (5/4/2021)
