Thank you for viewing. This is a set of 4 Ibaraki Prefecture manhole cards (Kasumigaura City, Tsuchiura City, Tsukuba City (English version), and Hokota 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. *I will also accommodate combined purchases with other cards I have listed. Please contact me if you are interested!!
