120pcs Breadboard Jumper Wires Assorted Kit - 10cm to 100cm Dupont Wire - Male to Female Multicolored Ribbon Cable

Good quality, correct sizing, plastic tips have quality wall thickness and the pins are sturdy. Great length options, perfect assortment pack. Easy to use pokes right in a fits snug.

Stranded copper wire and non-magnetic terminals. I assume the terminals are indeed plated brass. This is good. I removed one of the connector shells to took at the wire. It was easy to do with a needle. Just lift up the locking tap and pull the connector out. But be careful you only lift the locking tab as far as necessary so you don't "spring" it and the pin won't stay in the shell when you put it back together.

Has a variety of colors for easy ID of wires. I like how they're attached to each other, so you can easily peel off a group of how every many wires you need, such as if you needed 4 you can easily make a ribbon of 4 wires.

Good Product

I break them apart and cut some of them to solder the wire. The wire is copper so it solders well, unlike some with aluminum or steel wire. The ends don't look or feel so great but they the job... I would not recommend for heavier duty use on a breadboard, but for my occasional use they're alright. I plan to throw them away as they get damaged.
