RezBlock XL 30mL

RezBlock is designed to make residue and ash stay in the water instead of sticking to your glass so you can easily pour all that gunk out instead of completely cleaning your piece. RezBlock is made from a mixture of fruit extracts, vegetable glycerin, purified water, and citric acid to ensure that it won't affect the taste of your hit. Just add a few drops to regular water in a clean piece to prevent buildup, since all the ingredients are organic it is recommended to change your water regularly for best results. This 30mL bottle will give you up to 120 uses depending on the amount of water in your pipe, and the frequency that you change it.
