DICE LANGUAGE EXPLAINED:

D4, D6, D12 etc is a quick way of saying four side dice, six sided dice etc

A size in mm, usually applied to a D6, is the measurement of one of the die's edges. Which reminds me, one dice is not a dice , it's a die.

Custom Dice have always been a high value marketing aid but required large minimum orders.

Computer guided, laser technology has changed all that.

Now you can have as few as 10 custom dice made.
