Excellent wire!
Size: 2 Colors each 10FT, Style: 10AWG
This wire is very soft and flexible. Many strands and tinned nicely. A perfect upgrade for my power wheel wires that keep melting. These have been running for months in exterior environment without any issues.

Perfect for what I needed.
Size: 2 Colors each 10FT, Style: 10AWG
I used this wire for the umbilical cord from my truck to my slide in camper. The flexibility of this wire makes it much easier handle and route in between the cab and bed. I do have it enclosed in a flexible cover.
