This 18" Glycerin Straight Tube is built for extra-cool, highly filtered pulls with a freezable glycerin coil and triple perc setup. The built-in glycerin coil can be placed in the freezer before use to help chill the smoke path without needing ice. Smoke passes through a turbine perc, honeycomb perc, and matrix perc for multiple stages of diffusion, creating a smoother pull through the tall straight tube body. Finished with an 18.8mm joint, 5mm glass thickness, and Phoenix logo, this glycerin bong is a strong choice for anyone who wants cold hits with serious filtration.
