Silicone Slitted Diffuser Downstem | 13 cm
Stop replacing your tired, broken, and damaged glass downstems and give your bong a well-deserved upgrade with the almost indestructible diffuser downstem. The virtually unbreakable, non-stick downstem is constructed from heat-resistant, Food-Grade, FDA-approved silicone that is free from harmful plasticizers. This means it is safe to place it in the dishwasher for easy cleaning without worry of damage.
The downstem measures 13 cm / 5.12 inches in length and is compatible with most 14.5mm and 18.8mm female bong joints. This super bendy silicone downstem features diffuser slits that, when submerged in your bongs water, separate and filter the bubbly smoke for a cleaner, smoother hit that's less harsh on the throat.
The Silicone Slitted Diffuser Downtem comes delivered in a random color. What color will you receive? Check out our extensive range of smoking accessories available to order online today at GrasscityShop US.com.
