Review on 225pcs Heavy Duty Picture Hangers Kit with Nails, Hanging Wire, Screw Eyes, D Ring, and Sawtooth - Ideal Hardware for Wall Mounting Frames by Brent Peterson

hooks are very thin. I should have listened to the one star reviews but as I have ordered similar items before and they kept the paintings and paintings in place I ignored the bad reviews. But they are not made of the same material. We used a medium 50lb hook on a 10lb painting. The hook went down and luckily we adjusted it and caught it in time. Then I tested the other hooks by bending them with my fingers, they gave slightly! Absolutely unsafe for paintings of any weight.
