There’s something about a water pipe coated with resin that just makes us feel dirty. That’s why we change our water every day. But that is not the only trick. We also use RezBlock concentrate, which you add to your water to prevent resin from sticking to the glass, and instead floats in the water allowing you to pour out that gunk. Effortlessly keep your water pipe in pristine condition with up to 120 uses in this large bottle of RezBlock.
