The new and improved Invincipole Infinity series is an 18mm/14mm joint fitting downstem. It is precision crafted from an aerospace-grade aluminum module with a full-body hard-anodization and a sleek, satin finish. This device is best paired with the Invincibowl but it comfortably admits any 14mm bowl of your choosing. Invincipole features the world’s first Telescoping Technology extending from 3 inches - 5 ¾ inches, fitting a wide range of commonly distributed bongs. The Infinity series features the new pressure lock and release taper joints. The pressure responsive design secures your downstem into the bong then easily releases with a simple click anti-jamming operation, preventing the downstem from wedging in the bong. Meanwhile, internal joints provide superior holding strength plus easy bowl removal with a fluid twist and pull motion. The refined hex head allows you to maneuver the piece with little effort along anti-roll stability while cleaning. Precision lightning ridges make pole extension easy while the inner O-ring seals the directed airflow. The downstem also features a removable multi-hole diffuser cap that houses the final ash defense system, our proprietary stainless-steel screen. This high-flow mesh is reliable, effective, and enhances your smoking experience tenfold
