Awesome Dice online carries a wide variety of blue dice for all your gaming needs. Our polyhedral dice are designed forRPG gaming-- though we certainly have six-sided dice, we use those for flinging fireballs, not shooting craps. Every dice set from Awesome Dice is certified awesome, so buy your blue dice here!
We have blue dice in:
7-Dice setsof blue dice (D&D, Pathfinder, Earthdawn, Cthulhu, and many RPGs)
10 d10 setsof blue dice (World of Darkness, including Vampire & Changling)
36 d6 setsof blue dice (truly badass Shaowrun, Champions, etc)
Note that any dice that are substantially blue are going to be categorized as blue dice. Thus many premium dice that combine two colors would qualify as blue dice even though they have another color or two partying with them.
