Straight TubeWater Pipes or Bongs are usually a simple design, but extremely functional. They can be fitted with either a fixed or removable downstem depending on the specific design. The straight tube design does not leave a ton of room for percs but some of the larger straight tubes can be outfitted with honeycomb disk percs, turbine percs, and even some smaller tree percs. They're a great choice for those just starting out, or those who have been smoking for years. Start scrolling to see our wide selection of straight tube bongs throughout our online shop.
