I had the middle of two of my nails filed down to paper thin and they were not filed evenly, so now there's a weird dent in them and they look off at the edges. I did address this but was told it's fine (it's not as it means my nails are now damaged and look off). My finger skin was cured shut to my nail for several fingers and it was filed using a drill bit that's left one nail looking messy. My BIAB feels very uneven and I am having to get it redone to fix it.
