That little blue adhesive goes by many different names, but it keeps the world together. Thanks for submitting your skull to us. I checked out to Blu-Tack home page in order to find out more about this product. Did you know when not making skulls with Blu-Tack that it can be used for holding toll money to a motorbike. I read it on the internet so it must be true. Thanks again Sean and you should consider submitting this skull to their creative page.
