J Hook Glass Stem


    This 14 mm Grav Labs J hook is the perfect addition to your Water Pipe Adapter Kit. Now you can vaporize with a J hook as a complement to your water pipe.

    You need a male Water Pipe Adapter (mWPA) for this to be an exact replacement of the standard aluminum stem.

    The J-hook does not fit into either of our carry bags.
