Pops right on for a puffco pivot pen, I think they really improve the airflow and he has a carb built into the base that blasts fresh air into the chamber at a vortex. I made this green myself, there isn’t a similar green on the market. I think it reminds me of like a psychedelic celery. That face color on the flesh is this bass boat level sparkle blue that I just don’t get tired of seeing. Comes with some added bonus pack goodies.
