"Resin Preventer\nThere\u2019s something about a water pipe coated in resin that just makes us feel dirty. That\u2019s why we change our water every day. But that\u2019s not all. Not by a long shot. We also use RezBlock. Just a few drops help prevent the resin from building up. It keeps our pieces clean, and our hits fresh and delicious.\nMore Info:\n\nUp to 60 uses per bottle\nContains fruit extracts, vegetable glycerin, purified water, citric acid\nWon't affect taste\nJust a few drops needed with every water change\n"^^<http://www.w3.org/2001/XMLSchema#string>
