This basic set contains 10 pieces of each of 14 different lengths. The small transparent plastic case has 5 compartments. The amount of wire is appropriate for smaller projects.
Pre-cut and pre-stripped wires simplify and speed up breadboarding work. Having exactly the right wire lengths for the job also makes your projects much neater, more reliable, and easier to debug. These wires are compatible with standard breadboards that have 0.1" grids.
