Good marking ruler for precision, very good idea, but poor engineering. The thickness of ruler is only 0,3 mm & material not steel, but softer stainless metal, so very fragile in handling. Dye to small thickness sharp edges, prone to accidental injuring. Come in plastic packing, ruler (400mm) deformed somewhere in shipping - delivery line. Overall good for precision marking, only 4 stars for poor engineering. Hint - if you not need the longest 400mm version, better order shorter, 200,300mm. Less likely to be damaged in shipping process. Other - ad to order request for better packaging.
