This is the
spindown version of the twenty sided (D20) 'Kaladesh' die. This medium sized version is intended for printing in metal.
There is also a larger version available for printing in plastic.
The metal version of this d20 measures 41 mm (1.6 inch) from point to point, and 33 mm (1.3 inch) across opposing sides. In steel it weighs about 17.5 grams. The die is designed to be well balanced and to give a fair roll.
This version of this design has the numbers oredered in a spindown pattern, with consecutive numbers placed next to each other. This makes it easier to find the right number when using this die as a life counter in games such as Magic: the Gathering. If you are looking for a version with the numbers arranged as on a regular (RPG) gaming D20, 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.
