Handy for making wire harnesses or jumpering between headers on PCBs. These premium 24AWG jumper wires are a little over 20cm long and come in a 'strip' of 40 (4 pieces of each of ten colours). They have 0.1" sockets on either end and fit cleanly next to each other on a standard-pitch 0.1" (2.54mm) header. We recently updated these so they are in a 'ribbon strip' instead of individual wires. You can always pull the ribbon wires off to make individual jumpers or keep them together to make neatly organized wire harnesses.
