Straight tube bongs are a classic type of bong that provides a smooth smoking experience. They typically have less volume than beaker base bongs, which can be better for lung capacity. Additionally, most straight tubes have secure pedestal bases, making them just as stable as beaker bongs. Some popular brands include Envy Glass, LA Pipes, Grav Labs, Glow Guard, and My Bud Vase. Prices range from under $100 to $2,000 depending on the brand and features offered.
