The Wookah Hookah Valve Set is a great way to improve your hookah smoking experience. The set consists of two elements: a ball and a cap. The ball helps to seal the hookah and prevent any air from entering, while the cap helps to purge the hookah of any smoke that might be left inside. This ensures that you get a smooth, consistent smoking experience every time. In addition, the Wookah Valve Set is easy to use and clean, making it a great choice for any hookah smoker.
