Well there is SB and their like thirty somethin joint, and the mutli-perc downstems have at least a 29mm too.
look if a dime doesnt fit right, and your pinky barely goes in it is definitely a 14mm... and kevin good info i did not know that, and by SB sheldon black???
Ya sheldon black, they have some gnarly new pieces coming out, be on the look out. Really sick perc'd stuff, with multiple bores
Ya my friend just got one of the removable downstem ones, it hits so damn smooth. I also got a SB mini beaker, only 100 bucks and it packs a fat punch, nothing else gets me as high anymore, besides vapes.
