Secret Stuff® is an isopropyl alcohol-based liquid chalk. Rub a small amount on your hands, let dry, and a perfect layer of the highest purity magnesium chloride magically appears—and lasts. With less dust and mess, it’s the perfect "clean" alternative to loose chalk.

Plus, Secret Stuff goes further than regular chalk—it also cleans your hands, getting rid of gunk and grime that can build up while you’re working up a sweat.

"Started using this stuff as a base layer and find that I use WAY less powdered chalk over the course of a session. As an added bonus, my skin has never felt this good!"

Tim, FrictionLabs Customer
