The Fortune 18" Straight Glass Bong features a refined, stemless design and a water diffuser integrated throughout the tube. Each diffuser expertly filters and disperses the smoke into multiple bubbles, resulting in a smooth and flavorful inhale that is gentle on the lungs. The 18 mm female joint is reinforced and comes with an 18 mm male bowl for added durability.<br data-mce-fragment="1"> <ul> <li>Quality Borosilicate Glass</li> <li>Height : 18"</li> <li>Tube : 2" / 3.5"</li> <li>Thickness : 7 mm</li> <li>6 Pinched Ice Catcher</li> <li>Thick Bowl for 18 mm female joint</li> <li>Water diffusers</li> <li>Stemless</li> <li>2 Pieces</li> </ul>
