Medium size borosilicate glass bong
Medium-sized bongs have longer tubes than small bongs, allowing for more effective
cooling to filter out more impurities. Compared with a large bong, it does not hold more smoke due to its size and is more friendly to the lungs. Provides a smoother strike.
High borosilicate glass is cleaner and more heat-resistant than silicone and acrylic bongs. It does not produce harmful chemicals to the lungs at high temperatures and is easy to clean.
