GRAV 18mm/14mm Adjustable Downstem

Finally, no more measuring. Grav (formerly Grav Labs) has released an innovative new downstem that no longer requires guessing at the length you need for a proper fit. The Grav adjustable downstem will fit any 18mm female connection and adjusts from 4.5″ to 6″. Great for swapping between several bong downstem pieces too!
