These clips are strong. We use quite a lot of them in our office and keep having to buy more. Where do they go? The Staples price for this Staples product is swell. We are always looking for a good deal when it comes to shopping for our office supplies and this is definitely a good deal. And the clips are very strong. We have never had a problem with them not securing the papers properly. However sometimes when we clip them to something like the top of a binder they leave permanent depressions in the binder.
