Hema (Dutch departement store) always sells a couple of Jip & Janneke things. It's Dutch, so I don't know if everyone knows what it is. I've always loved the stories and have a couple books. More information here. Now they also have 3 polishes. A silver, pink and clear one.
It's a silver foil, opaque in two coats. I really like it and it reminds me of Orly Shine.
