Jameco Valuepro WJW-60P-R Wire Jumper Refill for Part Number 19290, 14 Different Lengths 10 Colors 25 of Each Length

Compared to other breadboard wires that I've purchased (that are very soft and bend when you try to insert them into a breadboard) these wires are great. Nice and stiff. They are cut to size and fit perfectly. I'm so glad to have found these. I'll be throwing out all the other garbage ones.
