I've only had my bong for 3 days and I've broken the downstem while cleaning. It was in a weird hand position and slipped and when I went to catch it I kinda smashed it down onto the corner of the sink..... SO NOW I'm in search of a 2 inch long (not measuring frosted) 18/14mm downstem (also, new to this.....if my bowl piece is 14mm and the downstem itself is 18mm..it's writeen 18/14 right? Not 14/18?)
