These are replacement pieces for the Ascent. these pieces are identical to the original ones, but because they are glass they are bound to break at some point so why not pick up some extra one incase that times comes.
The set includes one mouthpiece and one internal stem.
remove all of the glass from your ascent. Make sure you have discarded any loose herb. Allow glass pieces to soak in diluted ZEUS solution for around 30 minutes. Use a bristle pipe to get the hard to reach places. Rinse thoroughly with warm water and let dry before your next session.
