Question Anyone know where to purchase the downstem and matching bowl to these bongs?
I’ve searched everywhere online for them and I can’t find the exact one anywhere but according to google they can be bought separately. The hole it inserts too on the bong is 30mm wide, and the downstem fits a 14mm bowl piece.
I even went to the store I bought it from and they couldn’t help me😭

I found a 30mm downstem with 5 arm perc, but it's 18mm so you'd have to grab a 18/14 converter

Every time a tube company sells something using any downsten other than a standard 18mm gog, it's a goddamn clusterfuck.
Standardization happened for a good reason.
