Two limited edition castle stamps featuring Tsugaru Tamenobu's unification of Aomori. For those far away, please take this opportunity. These castle stamps were only available for a few months, and the locations for purchase were quite far apart, making them difficult to obtain. The Aburakawa Castle stamp appears to be the only one listed on Mercari, so it's a first-come, first-served offer with only one in stock. Please refrain from purchasing if you are overly concerned about minor imperfections.
