If you’re a fan of chemistry and all things experimental, this might just be the bong for you! This “Blaze glass” Premium bong which is made of pure pyrex glass of 7 mm thickness is nothing short of strong and this is proven by its weight of around 2 kg. This one is not for the weak at heart and requires strength to indulge into this experience. The bong hosts three vortex notches which allows air to enter the pipe and this facilitates the spinning of the smoke in a spiral direction as it forces to exit the pipe. This literal “Blaze Glass” is definitely a classic bong fit for a gong!
