There are different kind of water bodies available in the market, Genuine is a local one. Only you need is go to some good shop which got some variety and ask him to show all the water bodies which he has. Open the packets and see the finishing the one which looks more smooth in appearance, just select it and ask its price. I believe the one which yu have selected would be the most expensive one. Normally a good water-body cost around 15-1600 PKR.
