This is a transparent resin skull object. I believe it was originally intended for academic use, but I was using it as interior decoration. It would be great for a unique Halloween decoration if you were to place a light source inside. The head circumference is 51cm, making it a slightly smaller than life-size. It weighs about 365g. The top of the head, which is secured with metal fittings, can be removed. The lower jaw is also secured with a spring. The material feels a bit soft, like PVC, and has aged to an amber color. It also feels a bit sticky. Please refrain from purchasing if you are sensitive to this. Please understand that this is a used item. We only accept purchases from those who agree to no claims and no returns. If you have any questions, please ask in the comments section. Also, because many people do not purchase after a price change, I will not respond to [price reduction requests].
