Yes, in this thread:
Something your rarely see...
A friend of mine (forum member, I am sure you know which) collects them down in Baja but they are very difficult to drill. I take them to my partner in China and he has them drilled and matched. I just gave him another lot of about 30 strands last week.
Actually, as you rarely see these strands of naturals, I would not be surprised if the eBay piece is one we drilled. My friend is a natural wholesaler so it would make sense.
