Carry your keys on a belt loop (a month of use and I haven't dropped them once) or the strap of your handbag. It also stays put on the bottom of your pocket and you don't even feel it due it's small size.
It comes with a handmade Luava leather tag that doesn't take much room from your keys. It patinates beautifully so it's worth carrying a long time!
The size of the hook is 4,3 cm (1.7").
