I have bought a blank from them. Seemed fair. Claro can be about as pretty as wood gets, IMO. Lots of fire-like oranges and reds. It tends to be lighter in weight than black walnut from the middle or east of the country. This means it will be a bit softer, much softer than some of the dense English walnut. But much lighter in weight as well.
