Purchased from the National Palace Museum in Taiwan's museum shop (2017). The design is based on items in the collection. It's an A4 clear file, but it's 3D, so the contents are not visible through it (image 3). Also, it's quite rigid, so I think it's good for filing important documents. The motif on the front appears to be raised (image 4). I think it's difficult to obtain this item in Japan. #Taiwan #NationalPalaceMuseum #Souvenir #File
