I don't have any Inclusion or other fancy keyrings except for the pochette extender, but if I had an LV keyring, I would use it as a bag charm. I think it's less likely to get damaged hanging on a purse than actually using the keychain on a daily basis.
Actually I have to add to this, I have the black cell charm and despite the constant use and putting the phone in my bag/pocket etc. it still looks good. I've had it on my phone for about a year and a half now.
