These guys are amazing. I ordered some bone (for nuts and inlays) and buffalo horn(for knobs and bridges) and they sent me all kinds of stuff I didn't order. Some of it was synthetic, but perfect for picks. The rest was some really starnge stone and a block of "alternative ivory" (BTW, if anyone knows what that might be, I'd appreciate it. It's definitely some type of horn or tusk. It has the same smell and stomach turning effect that bone and ivory has).
On top of that, their prices are dirt cheap. Those black poles are buffalo horn. There's enough there to make a ton of knobs and they were only like $8 a piece.
I also got a catalog that was filled with some amazing inlays, binding, rosettes, etc.. I didn't see that stuff on their website, so I was thrilled to see that they sold it.
They're a small company, so I wanted to post this hear to hopefully get them some attention. Actually, I really just don't want them to go out of business because I plan on buying a ton of stuff from them<_< .

I ordered the stuff on the left and the stuff on the right was thrown in the box for free:
