This is a model figure I bought to study the skeletal structure. It's a set of male and female figures. The male figure's leg has a small ink stain. The arm and leg parts easily detach from the beginning. They come off depending on how you bend them, but I learned a lot from that, like "the arm wouldn't bend that way, so it came off." There are also spare hands and feet, so please consider purchasing them! I will wrap them in bubble wrap for shipping.
