The doobiewood® is an adapter between self-twisted and 9 mm activated carbon filters. Its tapered hole at the front allows the insertion of joints of different sizes, while the hole at the back guarantees a tight fit for activated carbon filters. The oil applied to the outer surface protects against moisture and other external influences. The company uses 3 different types of wood for its doobiewoods: American walnut - a durable and dimensionally stable precious wood from the north of the USA, olive wood or amaranth. Together with a flyer, sticker, pipe cleaner and three activated carbon filters, the doobiewood is packed in a cotton zipper bag.
