Together with each invoice we prove that
our leather meets with specific regulations concerning PCP and Azo dye stuffs.
Further more for most of our products we
have decided to test for other critical substances too, according to the so
called SG-standard. This standard gives you the guarantee that these products
fulfil a high criteria, so that critical substances, if they occur at all, lie
far below the officially stipulated standards.
Our leather which is tanned and finished
