From our innovative Kickstarter, Elixir dice are infused with glittery liquid cores that swirl when rolled. Each set is handcrafted and polished to keep their beautiful sharp edges. When the liquid cores are molded into the dice, the heat from molding creates a small bubble in the liquid core. Since the bubble in the liquid is constantly moving, we have not seen an effect on rolling. These full-sized polyhedral dice sets come with 7 dice (d4, d6, d8, d10, d10%(00-90), d12, and d20). We also offer these in individual d20's that sell very well on their own!
