GF-1 Glass Screens – Pack of 144
These small glass screens are molded into the shape similar to jacks, or caltrops, and come in a wide variety of fun colours!
To use these screens effectively, place the non-colored tip into your pipe or bong's bowl-hole, and the top part of the screen will provide enough coverage to prevent your cannabis from being sucked through, but plenty of room so it doesn't impede your inhalation.
Another added perk of these screens is that they are reusable and washable! Simply soak a paper towel in Isopropyl Alcohol or rubbing alcohol and wipe off the resin to your satisfaction. Each set comes with 3 screens.
