## Description

These Female/Female Jumper Wires are handy for making wire harnesses or jumpering between headers on PCB's. These premium jumper wires are 12" (300mm) long and come in a 'strip' of 20 (2 pieces of each of ten rainbow colors). They have 0.1" female header contacts on either end and fit cleanly next to each other on standard-pitch 0.1" (2.54mm) header. The best part is they come in a 20-pin ribbon cable. You can always pull the ribbon wires off to make individual jumpers, or keep them together to make neatly organized wire harnesses.

[Adafruit have tons of different Jumper Wires available, in all shapes and sizes!](https://core-electronics.com.au/prototyping/prototyping-wire.html)

**Note:** The length of the jumper wires is sometimes a bit longer than what is listed.

For best results, when plugging these in a line, have the sides with the 'silver latch bit' sticking out since that side is a tiny bit wider than 0.1"
