Hinatazaka46 ARENA TOUR 2025 "MONSTER GROOVE" Tokyo Performance TRAIN Campaign. This is a set of two original postcards from the Hinatazaka46 digital stamp rally. They will be shipped with protection against water and bending. I will drop them in the post within 24 hours from Tokyo. They will be sent via Mercari mail, which is trackable and delivers the next day or the day after (except in some cases), with anonymous shipping.
