Model is fine! It is a very good educational tool for young children as well as adults that like to know what there is inside the human body. Not for professionals. A 6+ years old, would definitely like it and have the challenge to disassemble and assemble all organs again. Nice idea to be unisex as well. The female genitals also include a baby in the womb! I would really love if this model was accompanied with a book that would have a description of each organ and it's main use (in color). Nice buy and really think it is an excellence choice from an educational perspective. YOUTUBE has a lot of videos but having an actual model 45cm height in front of you, makes a difference!
