This is a towel with a handwritten autograph from Mayu Tamura of Nogizaka46. It was a winning prize from the 2020 Dream Lottery. I contacted the official source in the past, and they confirmed that no documentation was available. It has been opened, but it has been carefully stored in a dark place, so I don't think there are any stains. Please refrain from purchasing if you are nervous about the condition, as it has been stored by a private individual. #Nogizaka46 #MayuTamura
