All I can say is.
After starting to create a keychain train.
I was annoyed at the sound they made when they dangled.
Now, I love it, I actually try to match my stride and make a beat as I walk.
I always am making noise so this suits me, hell, people refer to me as the LOUD guy in the real world, so.
That being said, I can tell you now, I actually add clip extensions to some keys in order to be able to open certain doors etc without ever needing to remove my keys from my hip or belt and so on.
That doesn't mean you are me etc.
Just my way of using them, so this thing at it's dimensions would suit me perfectly.
