This is a novelty bong made of approximately 930 grams of glass. The straight bar shape is classic. It has a 2-layer design, which reduces the burning sensation of being hit. There is a simple perc at the bottom. Pour water from the top to make it a hose for filtering. This is a work of art, not a glass bong just for smoking. It's a great option to give to a friend or relative as a celebratory gift. You can take it outside, use it on a trip, or have a happy hemp time at home. All bongs come with matching accessories.
