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.

Size: 2 Colors each 10FT, Style: 10AWG
10ga. wire in red & black colors as advertised. Product came quick & unharmed. The wire itself is perfect for finding its way through the contours of my vehicle becaue of its "rope-like" feel (unlike a stiff wire). Would buy again, because so far, so good. Hope that helps.

Nice cables, thick
Size: 25FT, Color: Black+Red+Blue+Brown
Great quality, but due to being CCA those won't fit most 10awg crimps, will need 8awg crimps.
