I have several Vernis Zippy wallets and I would highly recommend them. The Zippy in and of itself is a wonderfully designed wallet. 8 CC slots and lots of different slip spaces for other cards, or coupons and such.
I do not put receipts in them though. Some are light colored and I wouldn't want to get any color transfer on these beauties.
If I'm putting a light color Vernis into a handbag with a red lining, I use a small size purse organizer to, once again, prevent any chance of color transfer.
I've been carrying them for years without any scratches or blemishes of any kind. As long as this pre-loved one has been taken good care of I would say go for it. It's gorgeous!
