I'm afraid of a lot of things ... one is to lose my keys!
To avoid this nightmare, I'm using a keychain.
So far, it was a little difficult to remove the chain, e.g. if you want to use a key...
Now, with this belt clip, the keychain is pretty save but can also be removed very easy.
The belt clip comes without keychain!
There is another Belt Clip here.
This one is made of stainless steel.
