Each six-sided, square-cornered die is black, with the markings picked out in white. The 20 dice in this set each measure 16mm x 16mm. Each die features the Raven Guard icon on the 6 face, the Space Marine Apothecarion symbol (the Prime Helix) on the 1 face, and small bird skulls instead of the traditional pips on the 2-5 facings. The dice are supplied in a clear plastic crystal gem container.
