Review on 📸 Ultimate Hanging Solution: eZAKKA 47-Piece Non-Trace Wall Picture Hook Kit for Invisible, Traceless Picture Hanging by Carla Anderson

I live abroad where the walls are concrete, not plasterboard what these things are for. These are sold locally but I figured I'd get mine from Revain when I placed my order. You are not working. I tried 3 different sizes on 4 different walls and none of them went into the concrete - however they damaged the walls and broke the concrete when the small nails bent. I managed to insert one by tapping it gently, but the hook broke. I bought the pack from a local store (made abroad) and they work great so these aren't my walls.
