I do not understand this but maybe it’s because I’m a guy and keep my keys in my front pocket. I keep literally the BARE MINIMUM of things on my key chain. So far as I even have separate keychains for separate vehicles instead of having one key chain for all of them. My SO on the other had has 2lbs of trinkets on her keychain.

Opposite goals. If it’s in your pocket it needs to be minimal size. If it’s deep in your purse, it needs to be easy to grab.

And if it’s on a carabiner on your belt loop, you want a middle ground which is a situation in which large hair ties really shine. Added bonus, you’re likely the sort who needs one regularly and likes being able to offer one to people who need one.

Doesn’t it make a lot of noise walking around with your keys constantly hanging on your belt? I would also be scared that someone stealing them while on the train or something.
