strong small magnets

Have these magnetic locks ordered because I needed closures for chains. They are excellent for light chains. But I can very well imagine that they hold something heavier chains very well because they are very strong to me. I get the best magnets apart if I do not pull apart, but sliding sideways. The price-performance ratio is absolutely unbeatable. The size is also handy, they can definitely hold very well with your fingers, so they are not too small. Visually, I find the magnets also pretty, the values ​​the chain absolutely not starting. Hope that remain as beautiful shiny long run and will not be dark. From me definitely a buy recommendation.
