"I am happy to be associated with this merchandise. I still remember, in my childhood days, we were not really well off. I used to play with pens and pencils and used to assign them superhero status. Today, (through this line of merchandise), we are providing service to children of the world. It's a wonderful service," Hrithik said here at the unveiling of the merchandise.
