Total disclosure; I got those at a serious discount price. I would not have purchased those "fridge stickers" otherwise. But they work! Their actual surface is 3.75" x 5.5". It says 3 x 5 so that there is an edge around your photo. However, if your photo paper is thick, the adhesive on the edge is not that strong and it will peel. Recommendation : Print borderless 4 x 6 and trim with an exacto blade. I even removed the plastic cover. So the takeaway is that it works, but you may need to trim and plan ahead a bit. Result is very clean!
