This 20 sided die is numbered in a
spindown pattern, such that consecutive numbers are placed next to each other. This makes is well suited to be used as a life counter in games such as Magic: the Gathering.
The same design is
also available with regular numbering, in which the numbers on opposing sides always sum to 21, for use in various tabletop (roleplaying) games, such as Dungeons and Dragons.
The die is perfectly balanced to always give a fair roll. The numbers are cut out each face, which makes them stand out well against the surface. The die measures 40 mm (1.6 inch) from side to side, and 53 mm (2.1 inch) from point to point.
A slightly smaller version of this die, which is better suited for printing in metal, is available
here.
