That is exactly what they are. They are like a mini version of the WeRMemory Keepers pages for smaller books. They have 6x8, 4x6, 3x4 and maybe a few more sized openings to put pictures and memorabilia in. They also work with the Simple Stories collections which make scrapbooking a snap.
I am using one of the binders and the pages to do my December Daily album this year. Love all the colors they come in too!
