All Kinsho albums are crafted using acid-free, archival papers to ensure longevity of your photographs. The albums are covered in soft Japanese cloth, featuring a cover window with black accent mat, a back pocket to hold additional keepsakes, and a band closure to keep your album closed tight or act as a bookmark. Kinsho Pocket Albums are cute and portable - perfectly sized for sharing or making a treasured gift. Pocket Albums come with 12 sleeved sheets that hold a total of 24 photos. The 4"x 4" Pocket Album is a square format that's perfect for Instagram-style 4"x 4" square photos and makes a classy presentation in a contemporary size.
