3 x 3

You have no max hand size.
"The Potato Kingdom's unit of measurement.
We only use numbers, so it leaves everyone
guessing whether you mean 5 miles, 5 yards,
5 cups, 5 centimeters, 5 bananas, 5 blocks,
5 cookies or 5 distraction dances. Famously
quoted by Melissa when she said that size is
about 3x3."
