I just eat my shisha, I dont know what all this talk is about coals... those are for BBQ's...
I buy Nour. I dont know if anyone have heard of these but whoever translated the English side of the package... haha. "TO EASY LIGHT!" and "FOR WOOD COAL!" "Be may used burn to incence barbecue, or Narguille smoking for. Is not messy ."
There pretty good if you like natural coals. And a product of Syria!
