Review on Iconikal Magnetic Photo Sleeves: 4x6-Inch, 11 Pack - A Perfect Solution for Organizing and Displaying Your Precious Memories by Tiffany Tucker

I really like these cases. They are a solid sheet of standard magnetic sheet material (white on one side, magnetic on the other, slightly rubbery) covered with a clear plastic cover and glued on 3 sides. Each sheet measures 4 3/8" x 6 3/8" but the largest image you can place on it is 6 x 4 1/4. When you insert an image there is a nice white border on 3 sides but there is no real border on the open side (where you insert the image). If that bothers you (see the photo I posted as an example), you need to be careful to crop your photos to 4 inches (or less) so you get a more balanced look in the white "frame". .
