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.

Confirmed copper by measurement
Size: 2 Colors each 10FT, Style: 10AWG, Size: 2 Colors each 10FT, Style: 10AWG
There are many fake "copper" wire products on Amazon these days, which are not actually copper. Some are even supposedly tinned, but what is inside may be an alloy of copper like brass, so you can't even trust color or color of the cut ends of the wire. This wire, as of April 2021 at least, is actually copper, per 4 wire resistance measurement using Kelvin clips. A 10 foot piece of 10 gauge should read .01 ohms, and this wire does.
