Our Ultimate Gamers Dice are far from the ordinary. 16mm (2/3") is the most common size of dice and good for basic game play. But what if you have an extraordinary encounter or your group has explored and traveled for hours to reach the final destination? Wouldn't it be the right time to bring out the Ultimate Dice Set? Our Ultimate Gamers Dice are designed, cut and assembled by hand. Each die measures between 115mm and 130mm (4.5" to 5") in overall size. Each die has a unique pattern and number cut out or engraved (not a true balance). While they look great on a shelf, they CAN and SHOULD be used for that special game, or when the "Big" dice are needed to add something special to your campaign.
