Comments about Itoya Itoya Art Profolio Professional Presentation Book with 24 Sleeves for 8-1/4" x 11-3/4" (A4) Art Works.:
I purchase these books to hold A4 size trading portraits from music shows (basically large trading cards but made from photo paper). They keep my photos nice and organized and the covers are thick and soft enough to absorb and bouncing around during travel to ensure I get my stuff home in good shape. They also look great on a shelf.
The only downside is the pages are permanent so it is difficult to rearrange and you can't add pages. However I knew what I was getting so I could put up with the inconvenience for the quality of the item.
