I received this package during the raffle at MAHHA a couple of weeks ago. It looks nice, but I have no idea what this line is made of, how strong it is, or what it is meant to be used for.

Do you know what it is?

The number of strands (6) and length of each (9 ft.) suggests that these are meant for tarp lines, but I may be missing the true intent here. Any ideas about what this is and how I should use it are welcome!
