As another reviewer mentioned, the pack I got had uneven slots -- the top row being very roomy, the next row just right, and the bottom row too tight for a 4x6 picture

The top 2 rows are fine (if a little loose), but the bottom row is too snug - to the point where I have to actually trim a teeny tiny bit off my pictures to get it to slide in without being lumpy.
