I can't help as I don't use them but do you really need them? Over time they will do untold damage to your nails. Try going natural. Once a week give them a good buff and polish and apply a decent treatment to them. Then a good basecoat to prevent staining and finally a colour of your choice. If you keep up with buffing and polishing them they will look better than acrylics. Everyone thinks mine are false because of how good they look with polish on.
