Thank you for your interest in my listing. This is a pass case for a SECURITY ENFORCEMENT OFFICER ID. I bought it as a souvenir. Generally, it's a pass case for a USA security guard ID. It's not a police badge, but it looks cool. I think it would look cool to put in an employee ID, driver's license, My Number card, etc. A Suica card would be good too. The badge peeking out when you use it is something to be proud of. The reference item is John McClane's from Die Hard, but it's a sample and not included. Please enjoy putting in whatever you like. It folds in half and is designed to be passed through a belt and secured with Velcro. In Die Hard, it was attached to the belt of the slacks and hidden by the shirt. I would be happy to pass it on to someone who is interested or likes it.
