I bought the colored loose-leaf rings as well as the silver ones and found the silver to be of much higher quality. They were easy to open and seem to close securely.
The quality of this very basic product was all over the map. - Some where perfect; easy to open & close secured appropriately - Some were super loose and fell open under minimal use - Some could not be opened at all; the chrome coating bonded the ends of the clasp - Some had been riveted so tightly that it took the jaws of life to open them
