Using these dice is super easy. Just grab them from the plastic case and roll them on a flat surface during your tabletop RPG or board game. When you're done, put them back in the case to keep them safe. Make sure to roll on a clean surface to avoid scratching the dice. To maintain them, you can gently wipe them with a soft cloth. These dice are made of plastic, so avoid exposing them to extreme heat or sharp objects that could damage them.
