The key rings are pretty strong. The design is good and the two sizes give a good range of options to customize your keychain. The only downside is that it mentions that the nails don't snap every time you open the rings (in the product description) and the rings (especially the small ones) are so tight that you will inevitably tear your nails if you open them open enough. Get a key or any other ring (even male nails). If he hadn't mentioned it I wouldn't rate him but a promise is a promise and they don't keep.
