This Chain Reaction Fumed Hammer Bubbler measures 8 inches (20.3cm) long and features a worked design with spiral chain strands and exterior marbles, as well as fully fumed glass. Bubbler pipes can be a great crossover between traditional hand pipes and larger water pipes. Great for the casual or frequent smoker, bubblers require just a small amount of water and are just a bit larger than regular hand pipes with the added enjoyment of water filtration.
