Don't be fooled by the photo, they are very small, miniatures! However, they are excellent for their size. They easily stick to any wall and if you ever need to remove them, simply remove the plastic and the nail (which has no head) is completely stuck to the wall.

Perfect hook. With the guide it has, the hook "sticks" to the wall and all you have to do is hammer it in. It's small and discreet in case you want to remove your frame from the wall, and if the wall is white then it "disappears", without needing to remove it and leave a hole, so no hassle.
