Most of the ticket packaging has a short life, mostly they are disposed after the event. In this packaging mementos can be kept. With a perforated flap, which is provided with holes for a ring binder an album can be made.
If you don’t want to use a ring binder, the two small wings beside the holes can be used to connect several folders together. To see from outside which event it concerns, the perforated window on the front side can be removed, to show the title of the ticket.
