- Friction Labs- Secret Stuff
The original Secret Stuff, 45% isopropyl alcohol-based liquid chalk.
Secret Stuff® Liquid Grip Chalk is a high-performance cream that dries quickly on your hands to give you that fresh grip feeling throughout practice or a match.
Even when your over grip is wet, Secret Stuff keeps your hands drier, longer so you can serve, swing, volley, and slice without having to compensate for a sweaty grip. You can count on the original formula for the fastest drying time.
