Always very accommodating at VNA and my last varnish here stayed put on a one week holiday which was excellent. However it may have been because of the nail varnish I selected, but this time, the heat of the drying tool, made the varnish bubble and even after the therapist re-covered with a clear varnish to smooth out and then I used the cold dryer, the varnish re-bubbled and peeled off my nails that evening.
