Using Monster High Potions is super easy! First, open the 'crystal' skullette bottle stopper and take out the tiny charms. Untwist the skullette and drop the charms into the bottle. Then pour water into the potion bottle and shake it well with the 'enchanted' charms. When the liquid shimmers and swirls, it means the spell is working. Pour the 'magic' potion liquid into a cup to reveal the 7.6cm mini doll inside. You can snap the tiny charms onto the doll or the spiderwebby potion bottle for decoration. Note that the dolls cannot stand alone, and the characters, colours, and decorations may vary. Each bottle is sold separately, so availability might be an issue. Just keep the bottle away from extreme temperatures and dry it thoroughly if it gets wet to maintain it well.
