This is probably a stupid question:
I am looking for a (preferably European to avoid import duties) supplier, of the kind of blue-white wires similar to those used by Kato for the track power supply. I need to extend the standard track power wires while avoiding the relatively expensive KATO extension wires (263 Yen for less than 1 meter wire) as well as the KATO distribution box (see the pics below). I also want to use them to make my own version of the Kato wired Uni-Joiner.
