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 30 mm (1.2 inch) from side to side, and 37.5 mm (1.5 inch) from point to point.
A larger version of this die, which is better suited for printing in plastic, is available here
