Approximately 7 inches long not including the pins.
Easily separate wires to breadboard your project.

Each one of these ribbons has 40 wires with male pin at each end.

NEW unused

There are approximately 22 of these ribbons in this bundle so nearly 900 jumpers for you.

With a miscommunications I wanted to order 40 wires but ended up buying 40 ribbons. My mistake is your gain.

The whole remaining bunch for $20 or best offer.
