The Dice Lab calls its d120 "the first mass-produced injection-molded 120-sided die." The concept for this monster has been around thanks to a 120-faced geometric pattern called a disdyakis triacontahedron that uses an elongated triangle for each face. While there have been some 3D-printed attempts, it's been hard to get your hands on a d120. Until now.
Multi-sided dice are often used in tabletop role-playing games to build characters and determine the amount of damage in combat. The Dice Lab's fantastical creation is pretty substantial for a die. It has a diameter of 2 inches (50 millimeters) and weighs over 3 ounces (about 90 grams). It's available in red, black, green, blue and white. A single die costs $12 (£8.50, AU$15.80) and The Dice Lab expects to have stock available within a month or two.
