This album is beautiful. The leather, combined with the stitching and bow, bring this album to a very classy level. This is my first time using a ring-binder, and I must say that I really like it. I had forgotten that this was a ring-binder, and I didn't even notice the rings when I started loading the album. The pages are very easy to turn. There is enough space in the album for either thick pages, or to add refill pages. I plan to use the extra space to store all those little mementos from our family vacation (tickets, postcards, etc.).
