This is one ship stamp from Sado Kisen, the No. 15 company, commemorating the "World Cultural Heritage Site Registration of Sado Island's Gold Mines." The actual stamp has a date on it, but it has been marked out in white in this image. Please check the image and consider purchasing. The way the color and impression of the image appear may differ depending on your device. Please be aware of this. Also, the images posted are a bit dark, so if you have any areas you'd like to see more clearly, please comment, and I will add a more detailed image, such as a close-up. Shipping will be via Yu-Yu Mercari Mail Yu-Packet Post Mini or Rakuraku Mercari Mail. For Rakuraku Mercari Mail, I will use materials I have at home. I will take measures to prevent water damage and folding. I believe it is in good condition, but please refrain from purchasing if you are concerned or if you are a perfectionist, as it has been handled by a person once. Thank you for your understanding and consideration of purchase.
