ahhh yes that was the other thing they said. If anything with color gets on it it sets into it fairly easily or something like that.If you're not rough with your bags, then I don't think you'd have a problem. Just don't leave your bags in contact with things for an extended period of time because there is a possibility of color transfering.
I was going to buy and agenda in vernis and the sa did say one of the cons was it was a little more delicate. I am very careful with things but the way she said it threw me off a bit so I went with the damier canvas. I love the vernis pieces though. So pretty. I still might add it to my collection.
