Dice Unfolded Enamel Pin d4
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 d4 shape. It is about 1" (~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.
