Re: Metal head? srry, 1st time posting pics =/
It's hard to tell from the picture, but I believe what you may have is a bowl which was made for smoking tombak and other dryer forms of traditional moassel. Your probably not gonna get a very good smoke from such a bowl if your gonna be smoking contemporary, wetter brands.
And recent studies have shown that king moassel causes impotence in young men. So you should probably just stay away from such brands!
