This 2-in-1 precooler by Grace Glass is an awesome accessory for your bong. Thanks to the included glass nail and dome this precooler can be changed to accept both oil or herbs. An inline tree percolator splits your smoke six ways before separating it again throughout the slits on each arm. Comes with two female bowls, one for oil and one for herbs.
