Good Wire. Will definitely consider for the future.
Size: 2 Colors each 5FT, Style: 10AWG
Nice wire. Comes inside a plastic bag. Wire is soft and flexible. Worked as exactly needed for my boat wiring. It was easy to cut and crimp connectors on. It has a thick layer of insulation around the wire which keeps it from getting damaged.
