Parle G biscuit is one of my favourite old choices. Now a days I don't buy Parle G biscuit as there are so many other tasty and new rising brand biscuits are available in market which is much better than Parle G.
But I must admire Parle G biscuit as it was my regular snacks biscuit which I used to take with tea. It is a useful and tasty product of that time life(7-8 years ago) and it was so cheap. None other biscuit was such delicious at Rs 3 only. It was pocket friendly to buy and the packaging of the product was good. Hence it was easy to carry as the tiffin of my school going child.
I think Horlicks biscuit was the competitor of Parle G biscuit which also tastes good. But overall I don't like this biscuit now because of new and rising biscuit of this time.(example bourbon biscuit)
