The page protectors that are compatible with this album are:
Universal 12 x 12 Page Protectors
I have this album inthe 8.5x11 size, not the 12x12 size, but I think my comments apply equally here. These albums are well constructed, hold tons of pages (you can buy additional AC page protectors) and are very attractive. You can put a cute title or picture in the square in front. With the black color especially, I am sure that it will look good for years to come.
