I use these Presentation Books all the time. They are the best at keeping an important document together clean and at hand. I use all the sizes at different times.
I needed a portfolio with just this number of pages for guest info in our vacation rental. This product filled the bill nicely and is slim and smart. It's not easy to use: the individual pockets are well sealed with static charge and are tricky to open to insert your document. And it's very hard to slide the spine label out of its pocket to replace it without damaging the edges of the pocket. (Also I would have liked more choices in the color of the cover.)
I am using it to display my color gourd art creations on 8 1/2 X 11 paper. So much easier than trying to download my photos from i cloud and print as 4 x 6 photos at Walgreens. I love my new printer.
