These are designed to be used as beads for bracelets and necklaces. You can either do the five true platonic solids, or you can do the six common polyhedral dice used in roleplaying games -- it's up to you which way to go! (The dice approach, at least, lets you use the six rainbow colors... unless you're a big fan of indigo.)
After printing these, string them onto memory wire and bend the ends of the wire into a curl to make bracelets like I show. Or string them any other way you like onto anything else you like.
If you print one, please post an I Made One photo.
