i had 2 of these. i used the picture from the first one. the only thing that doesn't turn my fingers are sterling silver and gold, and surgical steel. It would probably turn my finger.
Yes. it is. there is clear fingernail polish or you can buy that spray clear cover in a can. it lasts a lot longer then the polish and you don't have to re do it as often. it's worth the price for the can.. i need to get one for myself.
