I usually get under the tag with a razor blade and slide it right up against the nail so the tag doesn't bend as I gently try up. They are usually loose enough. Go slow and gentle and you'll never know it was removed.

This is what I do as well,with a little wiggling they almost always work out fairly easily,  sometimes I use 2 razor blades coming at the nail from opposite ends.
