This is a educational construction kit assembled from various materials (plastic, metal, etc.).
Yep, here's that visable pig model you've always wanted! Touted as a "new type of puzzle," on one side it's just a normal swine, going about its everyday business...but on the other side, it's totally transparent, proudly displaying all of its internal organs and skeletal structure! Not only that, but you can remove and reinstall the bones and organs, for hours of endless fun (that's the "new type of puzzle" angle!). Of course, this is a very educational model, helping folks understand how living things are put together. Great for the junior veterinarians (or butchers) in your life! Model consists of 19 highly detailed prepainted parts with illustrated guidebook.
