Raked Fumed Buoy Beaker Bong Photography Favorites Flickr. Buoy Saves The Session This 8. 5" Buoy Beaker is designed using thick clear glass to form the pipe and its glass downstem, connected to a rubber grommet joint that creates an air tight seal. Raked and fumed glass accents are at its base to give the water pipe more character, despite its affordable price! It comes with a matching fumed glass "pinch bowl" style slide with a colored glass handle that fits into its downstem perfectly. This bubble beaker is made right here in the USA!
