This is a shirt exclusively sold to members of asense, a learning program founded by influencer ayano. Similar shirts were released by Shimamura, but this is a different item. I believe I purchased it for around 7,000 yen. It is new and unused, but has been stored at home, so please refrain from purchasing if you are concerned about minor details. It will be shipped via Yu-Packet Post. Please note that it will be compressed and simply packaged for shipping.
