Grav Labs 3.3″ 18.8mm to 14.5mm Fission Downstem

Another noteworthy result of a Steaphen Peirce and Grav collaboration, this Fission Downstem will soon become your most used accessory.

Upgrading on the standard downstem design, this piece features fission holes to further diffuse your smoke for a smooth and cough-free smoking experience. Designed with a tungsten rod while the glass is still hot, it has smooth edges that eliminate clogging. It’s equipped with a 14mm female joint. 

This 3.3″ long downstem is a great match for any 14mm beaker or a straight tube pipe with an angled joint.
