This is a educational construction kit assembled from various materials (plastic, metal, etc.).
This kit of the human skull, and everything inside, is a great way to see what's inside your head without having to pull it apart. The skull is divided into sections to be removed and examined to figure out what they look like, and you can even use it as a puzzle! A good way to quiz for anatomy and learn the layout of the skull. Includes a stand and assembly guide.
