Friction Labs says this about their Secret Stuff Hygenic Chalk Cream: Introducing the world's first Hygienic Chalk. Contains the concentration of ethanol (80%) recommended by the WHO, CDC, and FDA for Alcohol-Based Hand Sanitizer Products During the Public Health Emergency.
"I normally am not a fan of liquid chalk but this stuff is great. It goes on nicely, feels like silk and stays on better than before. 10/10 recommend. ALSO - it sanitizes, come on, how cool is that!?" - Lauren, FrictionLabs Customer
