Re: maybe i shouldnt have bought this..
I disagree about the vivi coal. They are hookah coal from egypt and are one of the best i tried.. you have to let them light up completelty before you place them on your bowl.
If you dont let them get humid they are great. But if you do, (you or the vendor selling them...) they give off a nasty smell while lighting up and take 10mins+ to light up.
As for green ash... what to say. i used them for more than a year and never happened to me b4
