Hello geeks! I have some trouble with shape filing on natural nails.. When they are a bit long and they want ballerina, tapered square, maybe almond or oval... How do tou file it? I think it takes a bit from underneath and I dont knkw why, it seems like it ripped.. I use 240 grit and go gently but still same result when it need to be filed a lot.. I dont have a problem with artificial nails, as you have a bit of a protective layer from the base..
