Review on BNTECHGO 14 Gauge Silicone Wire Kit - 25Ft Red/Black/White/Blue/Green 14 AWG Stranded Wires: Premium Quality by Patrick Ross

Fairly expensive per foot but good quality wire. If you're looking for flexible wire, this one should fill the bill. It is flexible, like the flexible probe of a multimeter. If you're familiar with multimeter test leads, you should have an idea of how flexible this lead is. When cutting, stripping, crimping, and splicing wires, remember that there are hundreds of tiny strands inside. Therefore, working with it is not as easy as with ordinary wire. But once it's connected to your project, you'll have the flex cable you want.
