These Metallic Dice Games' Elixir Liquid Core Dice are super easy to use. Just give them a good roll on a flat surface during your Dungeons and Dragons or other tabletop role - playing games. When handling the dice, be gentle to avoid chipping the sharp edges. To keep them in top shape, clean them with a soft, dry cloth regularly. Don't expose them to harsh chemicals or extreme temperatures, as this could damage the liquid core and the overall quality of the dice. With proper care, these dice will serve you well for a long time.
