These page protectors do not hold 12x12 scrapbook pages, especially if you put any dimensional embellishments on your pages. I had to cut 1/4 inch off each of my pages just to get them to slip in the protectors and my pages still curled and buckled.
I started out with a Pioneer memory book years ago as my very first scrapbook. These refill pages are so easy to use and they fit perfectly. I have never had a problem with them. I would definately recommend them to others.
