This is a set of six square-design cups and saucers. The manufacturer is unknown. The backstamp reads NKH NC'80. They have been stored at home for many years, so there are scratches and stains on the cups and saucers. There is also dirt on the underside. In photo 10, there is dirt inside the cup. As it was originally, the rim of the cup is slightly warped (photos 11 and 11). I am not a professional, so please refrain from purchasing if you are looking for perfection or are overly concerned about details.
