I find these pages are very sturdy. I love all the different configurations. It allows you to add pages when you do not scrap in cronological order or find other pics that should have gone with your layout that you missed. I find I have more pages in albums now rather than completed and lying around loose.
Beware ladies, these holders hold a lot, but do not have any sort of flap about the compartment to hold item IN!! I decided not to use the upper chambers and just use the middle and bottom and turn pages very slowly.
