Add your personal photos and memorabilia as well as pocket journaling cards. Photo Pocket Pages and Protectors fit in most 3-ring, 12"X12" albums. Acid-free and archival quality. Pages include (2) 6"X4" and (2) 3"X4" pockets.
 
Side note - I have tried these in a A4 WHSmiths lever arch ringbinder and they do fit inside. The top to bottom measurement is about 31.7cm. New holes would need punching in the pockets though for them to go inside a lever arch/ringbinder with two holes in the middle.
