Thank you for viewing. This is a set of 4 manhole design cards from Saitama Prefecture's Ryūiki Sewerage x 3 and Tochigi Prefecture's Ryūiki Sewerage. After obtaining them, I have stored them in a case 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 care. Thank you. *I also offer combined shipping with other cards I have listed. Please contact me if you are interested!!*
