I ordered several styles of the Becky Higgins 12 x 12 D ring photo albums and am very pleased with them. They are sturdy and can hold a lot of photo pages (I may have overloaded one and it handled it like a champ). The outside covers are sturdy and resist damage. I'm very satisfied with my purchase, especially since the price is terrific.
A fun design for an album. I ordered a different brand album as well and the Becky Higgins albums are a bit (maybe 1/2 inch) taller than the others. Not a problem at this point for me, but if you needed it to fit in a space, there are different heights to the albums.
