Things to consider before buying a bong or water pipe:
Flowers or concentrate? If you're a dry herb enthusiast, you'll want a bowl; dabbers need a nail to get lifted. If you're into both, consider a piece with an unattached downstem to adapt to all that the good plant has to offer. If you're looking for glass for dabbing; shop our dab rigs.
Size matters. Glass bongs come in 10mm, 14mm, or 18mm joint sizes. Not *those* joints; we're talking the glass pieces that connect the various parts of the pipe, and to make things more interesting, glass joints can be either male or female. Add in the many types of percolators, and the permutations for your new pipe are endless!
