To use these FC Barcelona Christmas crackers, simply pull both ends of the cracker apart gently. The contents inside, like the keyrings and photo clips, can be used right away. You can attach the keyrings to your keys or bags, and use the photo clips to display your favourite pictures. When handling the crackers, be careful not to pull too hard to avoid any damage. To keep them in good condition, store them in a dry place away from direct sunlight. If there's any dust on the contents, you can gently wipe them with a soft cloth.
