Roman Surface d4

This d4 is modeled after a Roman Non-Orientable Surface. Because the corners are rounded, this die should roll much more smoothly than a traditional d4. The number at the base is read, rather than a number on the corners, allowing the proper number to be read from any angle, and allowing the corners to be rounded enough for solid rolling. If you're into mathematics, or just like cool dice, this d4 is for you!
