These clips are probably good enough for what most of us will use them for - holding bags of chips or frozen veg closed after we've opened them. . However, I am disappointed in them because I bought seemingly identical clips from Home Depot for about the same price and the Home Depot clips were about twice as strong. These clips from Wideskall don't have the same clamping force as the HD clips and I noticed that right after using the very first clip. Again, maybe good enough, but not that good.
