This is a educational construction kit assembled from various materials (plastic, metal, etc.).
A super-detailed model of the miracle of life! Touted as a "new type of puzzle," this model features 27 highly detailed prepainted parts that can be removed and reinstalled, showing in detail the bones, muscles, uterus, and other vital areas around the pelvis during pregnancy...including the baby itself! Includes an illustrated guidebook (in Japanese) and a stand. Great for students of human anatomy!
