I'm from Oregon and looking to buy posters, or bong adapters. If you have any of these things private message me.
I have no clue what a poster is but aqua lab technologies.com have a bunch of different types of bong adapters under there "glass accessories" section, hope that helps lol
Hahahah I thought by poster you meant some other kind of bong attachment since you were asking about adapters too. But yeah me lhs has a bunch of cool posters, stores like Spencer's gifts probably has weed related posters too.
your in Oregon goto any head shop and if you live near Eugene i would go to mid town smoke shop that place is great and poster well maybe goto spencers?
