CLIPS Frame with clips
I have two of these in my apartment. I change the pictures in one on a monthly basis. The clips are easy to remove and the frame is easy to put together. The size of the openings for the pictures is almost exactly postcard size, so I tend to swap in strange postcards that my dad sends me. For a four dollar frame, it looks pretty nice. It comes with two mats - one with four openings, pictured above, and another with three openings, in landscape orientation. Put in photographs, postcards, random bits of ephemera.
