The hookah hose spring is a metal spring that goes onto the hookah hose near the hose port to keep the hose from crinkling. It also makes portable hookahs and handheld hookahs easier to use since you don't have to worry about the hose getting tangled or caught on something. The spring can be easily removed for cleaning or storage, and it's also relatively inexpensive. If you're looking for a way to make your hookah experience more enjoyable, a hookah hose spring is definitely worth considering.
