Review on 📷 RECUTMS 4x6 Photo Album – Black Inner Page, Button Grain Leather, Big Capacity Pockets – Ideal for 600 Pictures: Birthday, Christmas, Wedding, Anniversary by Kristen Simpson

All albums are exactly the same size. The only thing that differs is the number of pages you can fill out. I bought a 600 slot, 2/3 full, and the book wouldn't close properly. The manufacturer does not change the binding depth to accommodate the extra pages, which allows the 600-photo album to lay flat as it should. I recommend staying at 300/400. Also, the book is NOT leather, just leather, but quite durable considering it's only $20. You get what you pay for.
