Two stainless steel plates: one hairline finish and one perforated. Made of high-grade SUS 304 stainless steel (the type that doesn't stick to magnets). Very convenient for use over a kitchen sink. The perforated one is also perfect for a dish drying rack. This is a custom order. I no longer need it, so would anyone like it? It has been washed once. All sizes are approximate. Corner radius (R): 2cm Please check the other sizes in the photos. It will be shipped wrapped in bubble wrap. I will be away on weekends. If purchased between Thursday and Saturday, shipping will be on Tuesday. If you are in a hurry, please check in the comments section before purchasing. Shipping may be delayed before or during long holiday periods, so please check in the comments section before purchasing if you need it urgently.
