Inspired by role-playing and dice games such as Dungeons and Dragons, this set includes two versions of a d20 die, a shaded version, and an outlined version. For the shaded version, you use 5 different shades of the same color to create a 3D look and the numbers are done in a contrasting color, such as black or white. For the outlined version, this can either be done as a single color so that the numbers are holes in the design (as shown), or you can use a second color for the numbers.
