Secret Stuff from Friction Labs is an easy to apply, no fuss, no mess liquid chalk cream. Rub a small amount on your hands - at first, it looks like nothing's there, but after a few seconds, the moisture will evaporate and you'll be left with a perfect layer of the highest purity Magnesium Carbonate. Secret Stuff will naturally cleanse and disinfect your hands, killing bacteria and getting rid of gunk and grime that builds up over the course of your normal day and during activity. This unique cream will deliver chalk deep into the texture of your hands - as soon as you use it, you'll see how well it gets into every nook and cranny. A single 75ml Tube of Secret Stuff will last about 100 uses.
