This is the regular gaming
version of the twenty sided (D20) 'Kaladesh' die. This large sized version is intended for printing in plastic. There is also a smaller version available for printing in metal
The plastic version measures about 62 mm (2.4 inch) from point to point, and abput 50 mm (1.9 inch) across opposing sides. In colored nylon, it weighs about 5 grams. The die is designed to be well balanced and to give a fair roll.
This version of this design has the numbers in a regular gaming dice pattern, in which the numbers on each set of two opposing sides sum to the number of sides + 1. This type of d20 is typically used in role playing games such as Dungeons & Dragons and Pathfinder. If you are looking for a version with the numbers arranged in a spindown patters, please have a look here
The design of this die is meant to fit with the visual style of the latest expansion set for Magic: the Gathering, called Kaladesh. See here
for all my Kaladesh themed dice.
