This was a fun project to do with my daughter for educational purposes, but it was very poorly constructed. It did not come put together, which would have been fine but we never actually got it together. We eventually had to give up and tape it to make it stay closed. The intestines also won't stay in, no matter how you put them in. We tried higher or lower, and they still fall out. I only give this two stars because it did get the conversation going for our human body unit.
