Just like the Fill it, Shut it, Forget it bike (it was an advertisement of a bike from my childhood, I do not remember that now!) the following would be my picks for a very long time - atleast 7 to 10 years of holding time:
1. IPCA Labs
2. Ion Exchange
3. MCX
4. Johnson Hitachi Controls
5. 3M (I am holding unto a token 5 units I purchased back in 2012)
