What do you use your Cles for ?

Still use mine and always have one attached to my car key. Handy for keeping coins for parking/gym locker, car park tickets, supermarket loyalty cards etc. Or occasionally I use one to hold debit card, license etc if I want to travel very light.
 
Entry card to the office, a few coins "just in case" and a spare key to the house. I always have it in my purse and carry it in my hand or pocket at work.
