These premium jumper wires are a little over 7.9" (20cm) long and come in a 'strip' of 40 (4 pieces of each of ten colors). They have 0.1"(100 mils) plugs on either end and fit cleanly next to each other on standard-pitch 0.1" (2.54mm) header. You can always pull the ribbon wires off to make individual jumpers, or keep them together to make neatly organized wire harnesses. And with these features, these jumper wires are very suitable for Raspberry Pi, Maker UNO, breadboards, and other microcontrollers.
