Dusty matter

As soon as you unpack first error can be recognized. Without having it ever had in his hand are large brown spots on it and already dust in a mortar. Thought that it possibly comes from the storage and it has to be done only once clean. But even after cleaning the mortar and the first (10) attempts can be seen in my grated salt dark spots and granules. The abrasion of the mortar is indeed enormous and absolutely not appetizing !!!
Whether it is actually granite, I doubt it, since it hardly should be abrasion of real granite. Even if the part looks at first glance very good and its weight makes good impression, for me a "no go".
