Thee glycerin-filled water pipes are freezable, which makes them perfect for rapidly cooling smoke for smooth hits and large clouds. These pipes feature a fixed downstem and a bell shaped perc chamber, and they include a matching herb slide which is also glycerin filled and has an exterior glow-in-the-dark marble. Customers can convert these rigs to be used with concentrates by adding a 14mm banger nail. Colours may vary from images.
