10-sided dice

Each face has two long sides and two short sides. The five odd-numbered faces meet at the common vertex of their long sides. The five even-numbered faces meet at the common vertex of their long sides.

There seems to be a more-or-less standard configuration for the numbers on such dice. If I hold such a die between my fingers at two of the vertices such that the even numbers are on top, and read the numbers from left to right in a zigzag pattern, I get: 0, 7, 4, 1, 6, 9, 2, 5, 8, 3, and back to 0. (When I hold the die this way, the odd numbers appear upside-down.)

These dice are often sold in pairs. One die will be marked by tens from 00 through 90, and the other will have units from 0 to 9. The use of these markings is obvious; however, in practice, two dice of different colours may prove easier to read.
