Well, it is a bit cheap, but thats what I would expect at this price. It looks so cool. The enclosed chart is big, organized, easy to understand where organs go. Clear body is cool. Squishy organs are awesome. Te chest cavity and organs are exposed, so dust sticks to them. I just keep a piece of plastic that camewith it to cover the hole. It is so cool the kids cant keep themselves away from it. Perfect and so happy with purchase.  Highly recommend for homeschooling kids with.
