*This is an oxide in its unbrushed form. It is very deep black and subject to unavoidable sleeks and dull marks during handling. Functionally it is better than "brushed" oxide, which is far less deep, but aestheticaly better looking (brushed is supplied by special request only.) The marks in the black unbrushed oxide are <2% of the surface and affect the reflectivity <<1%. Appearance perfection is not guaranteed. Please speak to our sales department if you have a special request or concern.
