Kimber Kable Select

...thanks to rodman99999 too

How do I prove that I have what I have ? Photos ? 

When you post a classified you should definitely include photos of the actual cables.  And for the sake of all of our eyes, please use moderately high resolution and a flash if indoors so we can actually see the bloody things.  Read through other ads for speaker cables so you get an idea of the content people expect.  And price them realistically.  Unless they are current generation, used cables sell at a substantial discount from "retail", whatever that is. 

Substantial discount. So discount, say... 30% from the price paid ? 

If you've never been exposed to the internet market, you should start selling/buying some cheap stuff, get some feedback from buyers and than place for sale something more serious.
