Thank you for viewing. This is a set of 4 manhole design cards from Tsuchiura City x 3 in Ibaraki Prefecture, and Oyama City in Tochigi Prefecture. 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!
