I don't find my vernis cles very useful... it fits a lot less than my mono one and it's very stiff so it doesn't feel right to use the outside pocket along with cards inside it. I only bought it for the colour that I had to have. That wouldn't stop me from buying another one though! It just seems to be the least expensive SLG if you want to collect vernis colours that you "need". I much prefer the zcp... it's just a little more money but it's a lot more useful. The most used cles I have is my ebene simple card holder. It fits nicely into any pocket and is perfect for pulling out at the cash register without having to dig for anything. It holds my ID, main credit cards, and a folded bill.
