It what size downstem is this ? It's huge bigger than marker. I dont want the one that I have now eaither I want a strait downstem not the stupid 6 tree downstem it makes the bong I have suck its defiantly way bigger than 18 mm
18 mm maybe? Quickest way to find out would be to simply measure its diameter or take it to a head shop and try out a few sizes (that is, if they'll let you).
Its 18mm if a dime (actual currency) can fit in it. Otherwise it's 14. I've only seen bigger on, well, big ass bongs
