regular rings to turn on/off keys without sacrificing at security. The only two caveats I can think of are 1) the bands are slightly wider than most traditional rings. So if your rings have very tight holes you may have trouble putting them on and 2) they pull apart easily but the wider the space the harder it is to move them. This isn't a problem with most keys, but keys with a plastic-coated shackle (mostly bike keys and some car keys) can be difficult to spread wide enough to put on or take off. But if those warnings don't spook you, then you'll probably like these keychains as much as I do.
