"These Glass Bong Screens V-Shape are the perfect bong accessory for anyone who doesn't want to use a metal bong screen. The biggest advantage of glass bong screens is that they are re-usable, and there's no worrying about any funky metal taste. To re-use these glass bong screens, simply clean them with a bit of bong cleaner, isopropyl alcohol or benzine/petrol.
This pack contains 10 glass bong screens in V-shape with a diameter or 6mm."
