Review on 🖼️ EuTengHao 43Pcs Invisible Nail Screws Wall Hooks Traceless Picture Hangers Non-Traceable Photo Hook with Heavy-Duty Capacity for Hardwall Drywall - Multi Functional Picture Art Painting Frame Hanger (35Lbs, 6Types) by Lori Aguirre

I don't know the other walls, but these are perfect for the plastered walls in my apartment. If we use ordinary nails and a hammer on these walls, they will break into pieces and damage the walls. So I tried this and it works amazing. Also included was a small pencil and a small liquid to measure surface balance. It's easy to use, and the variety of nails is a big plus. A little loud knocking with a hammer, so watch out for your neighbors. You need to use a hammer or similar and hammer in vertically like all nails. Otherwise it will warp. It didn't happen to me, but I assumed it happened to others. Generally fast and convenient!
