Snake Eyes Yard Dice
Well, they're not polyhedral so these oversized dice probably won't add much to your roleplaying game night, but when the next big backyard Bunco fest or yooge Yahtzee extravaganza rolls around, the giant rollers will have your rolls covered. Snake Eyes Yard Dice are made of solid natural wood chosen for its longevity. And also probably for its non-toxic nature. In preparation for the night one of your drunk friends calls for a hard ten but gets a pair of dice in the fire pit.
Despite their name's suggestion that you'll come up short, Snake Eyes Yard Dice actually sell in packs of 6, stored in a drawstring jute bag for transport. Die measurements are 3-1/2" cubed.
