I put on nail polish often and I just swim a lot. It just suddenly comes off. Other then that, I don't think you have to worry since when my nail polish comes off, my nails are perfectly fine. But if you really have to get them off, then I don't know what to do. I once used this nail polish remover but, since you don't have one, I suggest you buy one. In about 4 weeks, I am sure that the nail polish will be gone. But I just wanted to say, the nail polish you have on souds really pretty!
