This collection contains bong bowls and slides with screens, including triple pinch screens, 4 holes, 5 or eve 7 hole slides, in both 14mm and 18mm! The point behind adding several smaller holes is to maintain the high airflow that single hole slides provide, but keep the holes small enough that no ash or flower gets pulled through - thus keeping your bong clean as a result. These screened bong bowls are great to use directly on a bong with no ash catcher, as they will prevent much from being pulled though. We provide all types of bong slides to cater to each smokers unique preference, so check our collection now and find yourself a new screened bong bowl to keep your bong clean!
