[1.395 lb] I use this Itoya Pro folio as albums for myself and have sometimes given them to family for fun. I like the 17x22 because it's the biggest size of paper my printer the Epson p800 can print. When I get a good picture, I print it and it looks nice in my album. I bet these are probably more for portfolio, but they make a beautiful album and are a great gift. I ran out of wall space to put pictures up a long time ago, so I just rotate pictures in my frames and have to put them in albums of many sizes.

[Polypropylene] This portfolio is perfect...I would certainly recommend it for displaying art

[24] I had a hard time, for whatever reasons, finding a photo portfolio with the exact dimensions for 16 x 20 prints. Then I remembered my friends at B&H Photo. One of the reps (always friendly, courteous, and professional) suggested the Itoya Art Presentation Book. The portfolio is high in quality and contains enough acid-free, perfectly clear, sleeves to accommodate 48 prints (24 sleeves for 2 back-to-back photos each). For the price, this is a beautiful presentation portfolio. I highly recommend it to all photographers who have a need to present their work in a professional manner.

[24] Wife and I have lots of larger photos great place to put them when not displayed in frames. Every few months we rotate the photos that are out in frames for display.

[24] Smaller size easy to store and show. Small enough that it's easy to present your photographs quickly. I carry one around with me in my camera bag.

[24] I tried a different brand as it was $10 cheaper from Amazon, and it arrived damaged. So, I decided to try the Itoya version of the 18 x 24 binder with the newer Evolution line since it was available at B&H and would arrive here faster than Amazon.
The product arrived safe and without damage (Thanks B&H). It was also about $1 less than the standard portfolio of the same size.
The quality is identical to the standard Art Portfolio in the best way. Having a few of them in different sizes, it felt comforting knowing it was the same quality despite the size difference.
It was a pain to put the 18 x 24 prints in at first, but this was my fault as I had no idea how to flatten these 18 x 24 sized prints. Once I learned, it was no problem putting the prints in.
The only differences from the original are the inner pocket (which I never used) and the edge. The edging of this portfolio is nylon stitching, which is supposed to add protection. Though there's nothing wrong with how the OG art portfolio handles the edge of the portfolio, I do prefer Evolution's nylon edge as I feel it adds protection.
Overall, I am delighted with the evolution, and I wouldn't be against adding more Itoya Profolio Evolution to my collection.

[1.395 lb] I love this product because it is light weight and always keeps my prints safe. I love looking professional when I approach potential buyers.

[24] Keeps my posters protected and in good shape

[1.395 lb] Perfect for print storage and presentation.

[Polypropylene] What I needed! I have bought all sizes of these to store my photography in. Better then where I was storing my photography AND if someone wants to view them it is easy!
