I work in the beauty industry and used a good amount of opi products...including the no chip line. The crystal file has never failed me. I feel it leaves the free edge nice and smooth. It's not overly rough like other files.
My first experience with this file was amazing. My best friend lent it to me and it worked so quickly without damage to my nails. I haven't gone back to a regular file and never will. Now I recommend this to everyone I know
I picked this up because I was tired of the cheap ones breaking and getting lost. I keep it in my purse and love it. It is reasonably priced for a long lasting file. It is not too rough and works better to smooth rough spots.
I absolutely love this nail file! It is so precise, and gets the job done quickly and efficiently. Although it is a bit expensive, I think it is well worth it. I would 100% recommend this product to others.
