I really appreciate being able to buy these in bulk, especially as I recently gathered all of my completed pages from around the house and various totes and began loading them all into albums. It's wonderful to be able to buy more than 10 (or even 20) in a pack.
I was a little worried when these first arrived, as I hadn't noticed the "3 Ring Binder" part of the description when I ordered. I was smacking myself upside the head, wondering how I had missed that, and was very frustrated at the thought of returning them. I took a chance and opened the box to try one, and they worked perfectly with my post-bound albums. No problem at all.
They are thick enough to be protective, but thin enough to keep some bulk out of your albums. Regular 12x12 pages slide right in, with 2 pages back to back. I don't use a lot of thick embellishments, but I do use some, and these handle those pages without a problem. They also accomodate my thickest challenge, which is 2 pages back to back, made with multiple layers of Club Scrap's thick cardstock and dimensional embellishments, with no struggle to fit the pages and no distortion of the protector or the page.
