There’s something about a water pipe coated in resin that just makes us feel dirty. That’s why we change our water every day. But that’s 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.
