Primary grade students in rural schools still use black-slate and chalk sticks to write with. After frequently writing and wiping the slate with their bare hands, it is common for the chalk powder to get smeared all over their hands. So Savlon introduced Savlon Healthy Hands Chalk Sticks – special chalk sticks infused with soap. These could be used to write just like regular chalk sticks, but the chalk powder accumulated on kids’ hands acted as cleansing soap when their hands came in contact with water. This simple innovation automatically turned washing hands with soap into an everyday habit without requiring any extra effort from children.
