1. Spin Dice take two hands to operate. In testing, gamers have said that since it is impossible to roll two Spin Dice at a time, it was more convenient to roll the D10 twice with the first spin representing the percentage die and the second as a normal D10.
2. While testing shipping costs, we discovered that in order to ship in a smaller shipping category, we needed to keep the dice sets in a package of six. This keeps the price lower and allows us to pass those saving on to our backers!
If you prefer to have the percentage die, we offer it in the $45 called 'One D&D Dice Set + A Percentage Die.'
