Can somebody explain the mm stuff to me I'm new to g on g. The description for my piece says it's 18 mm but the descriptions I see on some pop websites are for 18.8 mm is that all the same, are they just rounding down or up in the case of the 19 mm description?
14.4=14.5=14 18=18.8=19 Downstems are usually 14/14, 18/18 or 14/18. if you have a 14/18 downstem your bong has an 18mm joint and your slide is 14.
Hope this helps. ---------------------------- l14.4-14.5-14l l 18-18.8-19 l ---------------- \n-Love me some bong rips.
