About this Product
When holding in your hand this looks like a ball with lots of little spikes(92 if I counted correctly) hence its name. However it is in fact a very diferent D6. When seated on the table there is an upper pentagon shape made up of 10 spikes. Inside this pentagon is a circle of spikes which give you the value of the die face. 1-6.
