Thank you for viewing. These are manhole design cards from Tsukuba City, Naka City, Aizubange Town, and Isehara City. After obtaining them, I have stored them in a case and kept them in a dark place with the best possible care. However, I am not a professional collector, so please refrain from purchasing if you are looking for professional-level quality and management. Thank you for your understanding. * I am also happy to combine shipping with other cards I have listed. Please contact me if you are interested!
