I just wanted to write a quick post, in case you are trying to get your nails in shape for the wedding. I have been using one of the four sided file/buffers, and have had great results. If I don't use them, I often have ridges in my nails, and they break and peel like crazy, which I hate.The file, if used regularly, keeps my nails looking healthy and they grow without issues. I do mine about once a week or so.Just passing some info along in case it could be of use to any others.
