Awesome Dice carries a wide variety of blue dice for all your gaming needs. Our polyhedral dice are designed for TTRPGs. Though we use our six-sided dice for casting Frostbite as opposed to shooting craps, you're certainly welcome to use them either way. 

We have blue dice in:

• 7-Dice sets (D&D, Pathfinder, Earthdawn, Call of Cthulhu, and many RPGs)
• 10d10 sets (World of Darkness, including Vampire & Changeling)
• 12d6 sets (Shadowrun, etc.)
• 36d6 sets (Shadowrun, Champions, etc.)

Note that any dice with a substantial amount of blue are categorized as blue dice. Thus, many premium dice sets that combine two or more colors will qualify as blue even though there's another color or two in the party.
