Hi...i checked namebio with the keyword "purse" and got about 26 entries...but none of the search results had this (color + purse) combination.
speaking of end user, the pool for this one would have been a huge one had it not been restricted by a single color.
A few days ago, i was about to register this name, BlackCardigans.com, but then because of the end user concern as mentioned above...i did not register it.
However, luck, time and place is the key for any sale. I am a domainer just like you. Best of luck for the sale.
