A 7-set of large high-visibility polyhedral diffusion dice. Each set of R4I dice averages about 25% larger in size than traditional dice for higher visibility and better rollability!

The Arch'd d4 is a better alternative to the traditional d4; bigger, easier to pick up, and easier to roll than traditional d4s.

The Balance'd d20 provides a more even distribution of results by ensuring all adjacent groups of 5 sides add to 52 or 53.

Sets of 7 include Arch'd d4, d6, d8, d10, d%, d12, and Balance'd d20.
