O
To be honest with cables like that I would question the build quality of the whole of the kit and suspect any supposed CE marking or other supposed approval markings it might carry. I would consider putting the lot in the bin not just the cables or pass to trading standards and report the equipment importer.
Oh dear, can we just put this to bed. There is no China Export mark.You're right it probably isn't the CE European approval mark but the (so called) CE "China export" mark
