Each Archival Methods Caption Pocket 4 x 6" Photo Page in this 25-pack has two photo pockets per side, which hold four 4 x 6" images back-to-back. Each individual pocket comes with an acid-free white card stock that lets you mount smaller prints to the card. In between the two 4x6" pockets there is a center pocket with the same cardstock, which you can use to write a caption or note about the images displayed.

In addition, the pages have a 3-hole punch, which makes them compatible with 3-ring binders and albums. These pages are ideal for organizing and keeping track of many photographs.
