Original Ithmid Kohl With Zamzam Water And the kohl, God willing, is guaranteed, original, and 100% pure. This is my work. I buy it as a stone, soak it in Zamzam water for several months, filter out the attached stones, and then grind it. By the grace of God, it has been tested and many people have benefited from it. And my experience in it is more than 30 years, praise be to God. And I specialize in making original Ithmid. And God willing, I will fear God in making the kohl.
