I'm selling this because I bought it a few years ago and haven't had a chance to use it. Although it's unused, it has been stored at home for several years, so I've listed it as "like new." A set of blue and yellow clear books, A4 size, with 20 pockets each. - Color: Blue - Color: Yellow - Size: A4 size - Number of pockets: 20 pockets Thank you for looking.
