How to use: First, put on the Batman mask. It gives you the look of a real detective. Then, attach the detective case to your utility belt. This way, you can carry your evidence cards easily. When you find an evidence card, use the red reveal lens with the LED light. Just hold it over the card, and it will show you what's hidden. Attention: Keep the small parts like clue cards away from very young kids to avoid choking hazards. Don't expose the LED light to water as it may damage the function. Maintenance: If the mask gets dirty, you can use a damp cloth to gently wipe it. For the detective case and utility belt, a dry cloth can be used to clean them. Store the kit in a dry place when not in use to keep it in good condition.
