This little box has been designed specifically to take just two Ferrero Rocher chocolates, which fit snugly in a little containing tray in the base of the box.  As the title suggests, once the lid of the box is removed, the sides drop down and will lay completely flat which allows extra embellishments or messages to be placed, as a surprise, on the inside of the box.

There are still shots at the end of the tutorial which provide details on card sizes, scoring points and pattern diagrams.
