This is like liquid chalk w/o the chalk. Great for starting the day out to get a nice foundation, or after you've washed all of your chalk off for some reason. Cleans the chalk right off the bottom of my shoes as well. Bought it on a whim with some other stuff to get free shipping, but will continue to get more when this runs out.
Bought this because I was curious about it from its description. It works as described and gives a good quick clean. Ended up using it more for my shoes than hands since I blouder at a gym
