이런 제품도 있네요 너무 좋은거 같아요
I purchased this nail file on Naver Shopping in July. I like it because it is sturdy and not made of plastic. After trimming my nails, I use it to gently file the nail area, which makes them smooth and neat. It might be a bit dangerous for young people to use, but since it is made of metal, it is great because it won't break even if I apply force while filing.
