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 Christopher Todd

So far I've used them to hang a small 10+lbs <20lbs shelf on a concrete block wall. They hold up and they were extremely easy to use. I was a little worried that I would step on the hook and the plastic hook would break, but that wasn't a problem. The box contained a Fung Fu Panda pencil and a small spirit level that was literally just a bubble inside. plastic part. I don't really know how to use just a bubble as a bubble level when it's not attached to anything. Basically, I'm glad I found something that lets me hang things on cinder block walls without having to drill through them. .
