Chessex - 36D6 - Nebula - Nocturnal / Blue Luminary

I ordered the nebula blue luminary dice by looking at the picture which was pictured as a D20 dice set. The description does say 36D6 but I was shopping by pictures. The dice are very nice but it's not what I was under the impression I was ordering. The picture showed a D20 dice set, the description says 36D6.
