I knew that I wanted all of my albums to match and I didn't want my pictures to possibly get damaged from years of being stuck to a page. Also, I love the refill ability, the comment section on top of each picture slot, and the fact that my pages don't get stuck on binder rings when I turn them.
CAN YOU ADD MORE PAGES TO THIS BOOK?
Yes. Each of the extra page packets come with posts to add to the ones already in the books. You can actually remove the front and back cover in order to expand their capacity. I've got about 600 photos in the first book of this trio alone.
