Love this topcoat. Have been using it on top of a nail strengthener for years . Nice clear clean look. Manicures last about one week if I am not doing a lot of house cleaning. It is offered in this smaller bottle as well as a huge round bottle, have both and the smaller one is much more convenient  to lug to the nail salon. For some reason this topcoat hides any nail imperfections, such as white marks or small ridges... A must have for any lady or gent looking to have beautiful natural shiny nails. Enjoy!
