Kinder Joy is specially for children and available in all shops.
My brother, on watching its advertisement purchased kinder Joy. Its advertisement attracts small children, because they advertise it very nicely.
But, when he bought, I saw its packaging is quiet attractive but it tastes very bad. It is too much sweet in taste. Also it is very much costly. It attracts children by giving some plastic toys with it. But those plastic toys are not at all good.
All I can say, Kinder Joy is one of the worst product which have nothing good in it except its packaging. Also, it is not healthy. Purchasing it will only be the waste of money.
