About 6 months ago, I found out that Fullum & Holt had been re-branded as Sfalci. Well, I just received my new Sfalci Darek belt in the mail and I'm very happy with it.
The first thing that struck me is how light the belt is. It doesn't feel flimsy or delicate in any way, just light in terms of weight. It's made of super-soft calf leather, with leather backing. All of the edges are beveled, with nice even stitching running the length of the belt. The website says that all of the belts are hand stitched. I don't have enough expertise to say if that's true, but there's definitely a lot of attention being paid to the detail work.
I can't comment on how longetivity, because I just got it yesterday. It's going into the rotation starting tomorrow.
