There is a reason that Stacy Julian recommends these for her LOM class...they are very durable. They hold a TON of photos and the pages are easy to switch around if they aren't in the order that you want them to be. I haven't personally needed to add any refill pages (beyond what it comes with) to any of my albums (I stack similar pics 4-5 deep in one pocket so the binder fills up & there isn't any room to actually add refill pages to the binder). Highly recommend these albums. Not only did none of the pages tear while I was filling them but my 2, 4, & 6 yr olds have flipped through the albums & we haven't had any trouble.
