Hot Rod Glass PipeHot Rod Glass Pipe Hot Rod Glass Spoon Pipe Not to be confused with the Transformer, but just as awesome to look at! Made from hard wearing Borosilicate glass, the layered colours mesh perfectly well with each other enhancing the aesthetic quality of this premium glass pipe. The beads found around this piece not only project the flared quality of the artistic value, but provide grip for easy use and protection when placed on a hard surface.
