I don't know what to do and where to find it. In Slovenia no such wire (I know that it is hard to belive) exists... at least I can not find it. I turned upside down earth and sky but all I get is no, no, no. I even contacted a factory of wires but such tiny wire is not in a program. In despair I bought even a cable for telephone but wires in it are is much too stiff and big (0,5mm). I can not belive this either. As I don't speak german, can not search in this lenguage group. Can anybody in Europe help me with this? Where to find it!
