Insert one card per pocket to see both sides, or two cards per pocket, back to back, for maximum capacity. You can add more pages, too. The album cover is richly padded leatherette. The pages are archival safe with no acid, vinyl or PVC to damage your post cards, and the U-V barrier helps prevent fading.
