The document discusses gift boxes, which allow customers to purchase a box that includes vouchers for various activities. There are two main models - the European model where customers pay a flat fee for a box and choose activities, and the native English model where each activity has a different price. The gift box market has grown significantly in recent years, with over 6 million boxes sold in 2012 generating $1 billion in revenue across 20 countries. Gift boxes typically include a book describing theme-based activities and an exchange voucher. Customers purchase the box as a gift then redeem the voucher for an activity through a partner company. The largest gift box company generates $400 million annually with over 2.6 million boxes sold across 21 countries.
