75 flexible stranded core wires with stiff ends molded on in red, orange, yellow, green, blue, brown, black and white. These are a major improvement over the "box of bent wires" that are sometimes sold with breadboards, and faster than stripping your own solid core wires. Makes breadboarding super fast.
These wires have 'molex' 0.1" tips as opposed to rubber molded tips. They're more durable and stack up nicer next to each other!
