5 of 5 Finally! May 4, 2020
Reviewer: Anonymous Person from Escondido, CA United States  
My scrapbooks are two posts and I've had a difficult time finding 12x12 page protectors that fit. A text to Keepfiling was answered quickly with a link that gave me the right ones. No more searching the internet for me. I'm going straight to Keepfiling.

5 of 5 My search has finally ended!! July 31, 2019
Reviewer: Anonymous Person from Silver Spring, MD United States  
There are two essentials for page protectors for post-bound albums.  The pages must be flat and clear (unlike the wavy ones that come in most albums and are frequently sold in 10-packs at Michaels), and there must be an extended binding edge so the pages lay flat.   These check both boxes beautifully.  Thank you!!

5 of 5 No surprises! April 23, 2019
Reviewer: MRH from Merrimack , NH United States  
Keep Filing delivered! No surprises. I received just what I needed, at the best possible price in a very timely manner. I'd done quite a bit of searching for these over-sized page protectors, but ONLY Keep Filing has them.
