This arrived very quickly and excellently packed and is high gloss black carbon.. it has tape applied to underside and looks a class product. The unit has the M performance part number and made in Czech on the underside. Also supplied was a tube of presumably sealant / adheasive and an alcohol wipe. No instructions or other references to genuine BMW product.
I did not fit it, I had a body shop do that but it was flat went on perfectly and looks great on the car.
