You can’t have more faces on a die without losing symmetry and becoming a broken dice. The d120 is as large as you can go. Opposite faces add up to 121.
The dice is the creation of the The Dice Lab.
A single die will cost you $12 whereas a set of five sets you back just $50.
You may just want this die to complete your collection but do lt us know whether you’ve a RPG rule system that uses a d120.
