Push through the hole in the spine of this pack to reveal a drawer of die-cut pieces to make a fantastic free-standing model skeleton. The pieces simply slot together, needing no glue or tape, and can be stored neatly in the drawer after use. A 32-page book is attached to the front flap of this innovative format. Young readers will be absorbed by the incredible facts they learn, and the illustrated step-by-step instructions show them how to make the model with ease.
