Dice Unfolded Enamel Pin d20
Tabletop roleplaying games meet geometry! My Dice Unfolded pins show the "unfolded" net of each polyhedral die in a set!
This listing is for the d20 shape. It is about 2" (~5cm) long, has two back posts, and rubber clutches.
There are three color options: blue, purple, and black. You can also choose glitter or no glitter.
