I don't know how many of us would remember the 501, Nirma and similar soap bars that had become so much a part of life back in those days when Rin, Surf Excel or the fancy German detergents had still not entered the market. I remember people taking those detergent bars with them to nearby water source to wash their clothes. Much has changed now, but I still remember the fragrance of 501 or even Nirma. It has been years since I last saw one, though. Today, I stopped by a grocery store in a village on the way home. An auto driver was unloading his stock of "N S" bar.
