Are you a dice collector, teacher, or just a creative DM? Add a unique polyhedral to your dice collection with this d30, called a "rhombic triacontahedron." Measuring about 28mm point to point, bigger and beefier than a d20, the d30 is an interesting piece with a lot of imaginative applications in the tabletop RPG world. Randomly generate letters, dates, or generate d2, d3, d4, d6, d8, d10, d12, or d20 rolls using simple divison. Speaking of division, like all dice, it's also a great tool for teaching math. Several tabletop games are built around d30s, but they're also great life trackers for Magic the Gathering and other trading card games. 30 sides with visible optic white numbers on a classic solid cherry red.
