Inside out, color changing, borosilicate glass pipe. Orange, black, and blue cane, lines, and dots throughout the inside of the pipe. Gold and silver fumed for color change with color changing dots. Very thick glass with a flat spot on the bottom. Weighs 100 grams. Just over 3.75 inches long. Pictures were taken in the sun so the pipe is darker in color in indoor lighting. top
