We've taken the classic beaker bong and cranked up the cold. For those new to the glycerin bong game, this is your go-to: low maintenance, user-friendly, and hits so chilly they'll make your old ice cubes jealous. When you take a drag smoke is cleansed via water filtration before gliding through a frosty glycerin chamber that leaves harsh smoke and coughing fits a thing of the past. Enjoy a righteously smooth bong and simplicity with this tried-and-true piece.
