The knockout punch. This piece takes what a gravity bong is to a whole new level. I call it the knockout punch because that’s what it does one hit and your out. Designed with 360° rotating glass. Comes with an aluminum bowl kit,a glass liner, a 3-foot silicone hose for a direct hit,and can also connect to any smoking or vaporization device with a 14mm male joint.
