I plan on having these in the store too. It's essentially a 1" wooden block with some really nice labels stuck to the sides. Then I did some drilling and rod rigging and now its mounted in a dome display case and looks awesome. It's also incredibly sturdy feeling (not a paper craft feeling). If I weren't worried about the labels getting worn out, I'd totally make these into dice.
Since I only have four of these domes for the time being, the number of mounted ones will be limited in the store.
