Breadboard jumper wires are great for quickly assembling a circuit on a solderless breadboard. Each kit contains several different 22AWG wire lengths pre-bent and tinned; the wires are color coded based on the length. Since these lay flat and are cut to length, this style of breadboard wire tends to provide an organized, easy to follow, layout on the breadboard. These are shipped in a segmented storage case to keep them all organized.
