This ad features a 4 1/2" HAYLEY'S COMET II comet glass smoking pipe with AN iridescent silver fuming, red/burnt orange and dichro comet spiral ribbons, 3 gripping features on the right side and an air control hole on the left . This pipe is great looking, portable, easy to smoke and a good addition to your collection. Over-all a good compact pipe. Like all chameleon silver fumed pipes the exact hue and glow from the pipe depends upon what background color you hold it against and the light source. When viewed against a black background (hold it against your black shirt to see an awesomely cool purple iridescent glow) it glows a purple iridescent color, against a white background it has a blue-yellow iridescent glow - a very cool and unique property of this unit. Keep in mind that these pipes are hand made and they will have natural variations that will make each unique, but always beautiful. This pipe is about 4 1/2" long, with the head end of the pipe shaped as shown and about 1 3/4" wide with an air control hole on the left. The tobacco bowl itself is about 5/8" diameter x 3/4" deep. The stem of the pipe is about 3/4" diameter just under the bowl tapering to 5/8" in diameter at the end of the stem by the mouthpiece. This pipe is for tobacco use only.
