The Flower Head with Glow Dots Glass Pipe has a few interesting features. First, you’ll notice the inside out designed flower pattern inset on the head of the pipe. This is backed by assorted glass frit colors, including blue, green, red, etc, to make the white of the pattern stand out. Then, glow in the dark glass rod is used to create a line of dotted marbles from the mouthpiece, up the neck, and to the bowl. Finally, you’ll find that the glow dots also react to UV/black light, as well, and turn a 3rd color. The dots appear white in regular light, greenish when it’s dark, and blueish when you shine it with black light. It’s like getting 3 different looks in one!
