Dice Unfolded Enamel Pin d10

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 d10 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.
