Swatow handkerchief. This item was kept at my mother's home. My mother never used it and stored it in a bag. However, it has been washed, so the surface is not flat and has some slight imperfections as shown in the photos. It is not a perfect square. It's a pure and lovely handkerchief. Please consider that it has been stored for a long time and judge based on the photos. If you understand and accept this, please consider purchasing. Thank you.
