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 and then easily releases it 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.
