This is by far the best I have used to hang photos on. While installing, the nails didn’t bend as it did with the other cheap products. It was perfectly made and can definitely hold a big size poster. Have attached some examples to view.
This product is excellent. works really well without any drilling. you just need a hammer and some patience. My wall was bit hard surface due to heavy concrete still half the pin went inside the wall which is enough to hang anything. This can hold pretty decent weight according to plastic tip. Some areas the pins went complete inside the wall and at some places after the half point pins started bending. But you just need that much to hold the frames. I would recommend this.
I bought this hooks for hanging some photo frames on my hard laterite stone wall. I came to this after I made a big crack on the on the walls when I drive nail with a hammer. I am satisfied with this product as it does the job well done.
