And then we just see the high quality brand products from Oehlbach and Co. Unfortunately, many are of the opinion that quality is to have cheap and order rolls at a price of 0.4 cents the meter and believe to have high quality goods based. Unfortunately, the names of these products are also often omitted to let the customers in the dark. Here is pure copper in a neat insulation.
