In the world of bongs, Wave is one of the best known brands out there. Their bongs are top of the range, with cool designs and excellent smoking features. The Wave Glass Offset bong is no different. It is made from clear glass, so you can see the smoke traveling up towards you, entrancing and enchanting. At the same time, however, it comes with an offset where excess tar is collected. While smoking is never going to be truly healthy, this bong will at least make it less unhealthy. Plus, it is quite eye-opening to see how much tar actually collects in it.
