This is a female version of a synthetic human. It's a second-hand product. I used it for a short period to study design. The stains and dullness you see are part of the product's specifications. There are no issues with movement, and you can pose it freely in various ways. Also, I'm not sure if it's an individual difference, but the torso part is loosely fixed and moves around a bit. However, it doesn't affect posing. Please be aware of this if it concerns you. It's the part circled in the photo. All other parts, instructions, and clips are included. Feel free to comment if you have any questions. Price negotiations are not possible.
