7-sided DICE with PIPS

I didn't try yet if these 7-sided dice (D7) are completely fair. The size and shape of faces 6 and 7 are different from the others.

A great 'ball roller' with the possibilities 1, 2, 3, 4, 5, 6, and Grolsch (a Dutch beer brand).

Have a look as well in DICE from GERMANY to see the so called Y2K die, which can be regarded as a D7.
