If you bought it locally, then it probably comes with a case blah blah blah blah. They probably just forgot to put the downstem in the case. There is a international exchange place in Las Crusas about 40 minutes from where I live and my friend bought his hookah there. I was with him at the time and told him to remind them about the downstem because when they were on display the downstems weren't screwed in. So he did and they were like whoo! Good thing you reminded us and he got his downstem. The end
. No really though you should ask them.
