If you work with electronics components, you will definitely recognize these alligator clips with wires. Two alligator clips are connected by a wire so that you can clip on to parts. You get 10 total wires (2 red, 2 black, 2 green, 2 yellow, and 2 white). Each 20" lead has 2 clips . These are great for prototyping, repair work, or just to have around.
