The brightly colored giant dice come in counts of 12 that are each 2.5" in length and 2.5" wide. The brightly colored giant dice are perfect for making board games extra fun. This package contains green, red, blue and yellow dice. I'm thinking one giant game of Yahtzee is necessary with these. These giant dice are made of a quality foam. For anyone ages 3 years and up. Includes 12 giant dice.
