ok, so I just picked my first bong up from a friend yesterday. supposedly it's like an 80 dollar bong that he sold to me for 25. but there is a reason it's so cheap. it has no grommet, downstem, or bowl. I also have no clue if it's GonG. I need any information or links possible to get this bong back to doing what it does best asap. I've researched around, but I figured it would be best to just upload pics and get a direct opinion to avoid any costly mistakes. If I measured the diameter correctly, it's 20 mm. I need any and all measurements you could possibly assume by these pics. And no, there is no head shop anywhere around me. I live in the country. I do not know the brand of the bong either. it's made of glass.
