Yes, they will survive the summer holiday and not at all they are going to be ruined. I have heard from many, that they are afraid if the salty water will ruin their artificial nail. However, this fear is unnecessary. For those, who have gel artificial nail, that is not soluble with anything. For those, who have porcellain artificial nail, although it is soluble with its own porcellain-remover solution, but we apply on both material’s top an insoluble covering layer, as conclusion of the artificial nail construction process. This alone can guarantee that the nails will remain intact, like they were even bomb-proof.
