Anyone ever buy these? I am interested in the size. How big are they, as in length? The beef and the lamb bones. Are the lamb bones femur bones too?

They are ridiculously expensive. Find a butcher and you can get the same bones for 1/2 the price.

We have a butcher. Only one in town and he pretty much charges the same. His meats are local, hormone-free, natural. So he charges premium.
Cost is not the issue. Size is.
