Review on 120PCS 10CM Dupont Wire Male to Female Breadboard Jumper Wires - 3 Inch Length by Sohini Ledesma

Ordered these because they say "Pure Copper". They are, and they pick up solder perfectly when you need it. I only ordered these because I didn't notice people saying the other brand was copper plated aluminum until they arrived so I ordered them. Another brand also happened to be copper, so I now have a lifetime supply! Overall I am happy with my purchase. This is a great price for a large number of wires. Hopefully they will last a long time with multiple uses.
