What makes the dice different?
Unlike many games, the dice in Star Wars: Destiny do not use stickers. Instead, the dice are plastic-injected like normal dice and rolled in a tumbler to add a fine, smooth polish to every die. The images on each side are then physically heat-pressed onto the dice, essentially printing the artwork directly onto the plastic. Finally, the die is covered in a scratch-resistant coating, allowing you to roll these dice without their quality deteriorating.
