The Citadel has durability you have to feel to believe! 7mm glass creates a highly-durable foundation for this pipe so you can enjoy it for a lifetime. Two chambers are included to provide maximum filtration to smoke, because filtration = smooth rips. Starting in the bottom chamber, a 4-armed spore perc has many holes for smoke to pass through water, before it travels up and meets the unique cylinder-shaped perc! This percolator doubles as a splash guard, and features several slanted slits on the inside and outside for maximum water-smoke contact. This premium perc tops off the filtration process beautifully, delivering a silky-smooth rip. The design of this bong is stunning and modern, featuring multiple matching-colored engraved Arcatek logos and patterns on the base, chamber, neck, and joint.
