Base and top coat of very good quality. Important as this is the part in contact with nails and outside (varnish protection). Lets put a varnish (suitable) of another brand between. I keep more than two weeks. To remove, pure acetone removers on cotton cut in half, placed on the nail, wrapped with aluminum foil, exposure time + -10 minutes and he gently removed without damaging the nail (use the utensil appropriate manicure). If the lacquer layer has a thickness, after removing a part, replace the cotton on the nail 5 minutes. Place a cotton ball with acetone on each nail to finish. If I do not return immediately varnish, I treat my nail with pure organic argan oil to rehydrate. Tip: use a 12V LED machine instead of UV, seem less harmful to very short exposure of skin and time (30 seconds).
