These pipe screens are made of Brass Mess, that allows free flow of smoke and air while keeping dirty, harmful ash from pulling through your pipe. Pipe screens prevent clogging and stop hot ash and embers from entering the inner pipe, making smoking more enjoyable and cleaning a much easier task. Pipe screens are durable so they can be cleaned and reused or can be replaced as needed to support maximum air and smoke flow. Each and every Beamer Pipe Screen is meticulously crafted for easier smoking and clean up and no tobacco in your mouth! Our Attention to Fine Detail makes us second to none. Beamer has been Crafting Mouth Watering Flavors & Smoking Accessories Since 2010 AND SOLD IN OVER 55 COUNTRIES!
