These hangers are made from grade 201S stainless steel, which is closer to grade 304 than 201. The size is 31cmx20cm. ATTENTION PLEASE: This badge of hangers came with a fault: The little connectors, that connect the wire pegs to the hanger frame, are not made from grade 201 ss material. Because of that they fairly quickly develop some surface rust if left outside for some time. For this reason they are made available extremely cheap.
