The page protectors that are compatible with this album are:
Colorbok 12 x 12
I can't tell you how much I love these albums. This is my go to album. Love love love. I can't say enough about the product. This is the one and only album I have been using for the last 10 years or so.
I love the fact that this album indeed fits 12" x 12" papers without any trimming. I only have the one black one. I have not noticed any problems with its cover becoming disheveled. The pages all lie very nicely. I have not opened it up and added or subtracted any pages and probably won't since the album I have is completed. My biggest disappointment is that I only have to one... and will be forced to buy more of these to complete other projects.... :)
All the Colorbok Perfect Scrapbooks are great...good quality and nice 12x12 page protectors that actually fit 12x12 lo's.
