I still have a considerable amount of Black and white.. especially for veneers but it is disappearing.
My supplier, the only importer of it in the country has told me.. a few years ago, that they may not bring any more in. It is getting too difficult as the delays in shipping and receiving are causing too much damage to the wood.
Four years back, they lost an entire load. Most exotic hardwoods can't be kiln dried and are shipped "wet".
Black and white is extremely tricky until it is under 20%. At that time, it can be persuaded a bit.
It is one of the most stable woods I've used once it is dry not to mention beautiful!
