This Frosty Fog Glycerin Bubbler from Pulsar measures 6.25 inches (15.9cm) tall and has a glycerin-filled base that can be frozen for extra cool smoke sessions. This hand pipe features a stand up pipe build and is dotted with decorative purple dots. 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. Colors vary.
