Sets of 7 now include the following dice in a display box:
Arch'd4, d6, d8, d10, d%, d12, Balanced'd20.
The Arch'd4 is a better alternative to the traditional d4; bigger, easier to pick up, and easier to roll than traditional d4s.
The Balance'd20 provides a more even distribution of results by ensuring all adjacent groups of 5 sides add to 52 or 53.
Each set of R4I dice averages about 25% larger in size than traditional dice for higher visibility and better rollability!
