Albus Album Pink has 2 sheets on one side, and 5 sheets with both sides usable. This is a new, unused item, but I have taken it out of the bag once to count the number of sheets. Green has 2 sheets on one side, and 21 sheets with both sides usable. I have put photos in the green album once, but since I bought it recently, there are no stains or yellowing, so I think it is a beautiful item. Please understand that it is a used item because I have put photos in it once. The green album has additional refills, so it also comes with connecting screws. There may be small scratches or dirt, but nothing noticeable. Size of photos that can be stored: Square size Number of photos that can be stored: Pink 76 sheets... Green 264 sheets
