MUJI A4 Wide 40 Pockets Transparent Clear File Ideal for organization. - Quantity: 8 books - Color: Transparent - Type: Clear File Thank you for viewing. I used these when collecting idol clippings. I put each clipping in individually, so I think there is little damage to the files. There is no visible color degradation, but please be aware of this if you are sensitive to such things. m(_ _)m
