Glass tips are used just as a paper filter is used, but safer and healthier. Each hit will filter through the glass enhancing your smoking experience. Glass filter tips also keep the heat level down so you can enjoy a slower, quality burn, all the way to the end without worrying about burning yourself. Using a glass joint tip, you can avoid soggy paper filters & restricted hits while stopping hot ash and resin from getting into your mouth. You can reuse glass tips for years to come, just remember to clean between uses for optimal results.
