Large High-Visibility Polyhedral Dice: Holi-dice
Sets of 7 include the following dice in a display box:
Arch'd4, d6 w/ symbol, d8, d10, d%, d12, Balance'd20.
The Arch'd4 is a better alternative to the traditional d4; bigger, reads from the top face, easier to pick up, and easier to roll.
The Balance'd20 provides a more even distribution of results by ensuring all adjacent groups of 5 sides add to 52 or 53.
