With a shape inspired by geometric crystals, this 4 sided die from Crystal Caste is anything but traditional. Unlike the classic pyramid D4, this die requires no explanation for new gamers. Number from 1 to 4 a single time around the die, the face of the die that shows up is the roll (unlike the classic D4 with three numbers per face).

This die measures 30mm from tip to tip. Each face of the die is rectangular with a single number (measuring 12mm by 20mm).
