Make the most out of your four-ring photo album by filling it with 10-slot archival photo pages. Each of these four-ring album pages can hold up to 10 4" x 6" pictures. A pack of 10 pages increases your album's capacity by 100 photos. Each side features enough room for two vertical images and three horizontal ones. These photo-safe album sheets are ideal for a brand new photo album purchase or as extra storage space for an album that you've filled.
