Unfortunately, it was my worst experience so far. There were 2 woman working with 3 clients, one of them could not remove the old shellac and cut my finger while manicure, peeling the nail off, I want to mention, that none of the instruments were NOT disinfected, so if I get some bacteria or a swollen finget, ill forward myself to the Ordnungsamt.
The quality of the nail lack covering is poor, they don't have enough colours and most of them are gone, while doing the shellack, they step big from the finger cuticle, so I guess the manicure is going to grow up within few next days.
