This is a preorder estimated delivery is 1st July bit long of a wait but worth it I think as the set is listed on booktopia for $63.50.

Or you can find them $6 each from BigW or Kmart but hard to find the complete set.
This Peep Inside gift set includes six beautifully illustrated lift-the-flap books.
Young children will love peeping under the flaps and through the hole in the pages to discover what goes on at the zoo, in animal homes, on the farm, in the garden, at night and inside the world of dinosaurs.
Thanks ordered one.
