There is a reason that most nail salons use OPI polishes exclusively; these are definitely high quality products.  When I paint my nails with OPI, I find that they look good with minimal touch-ups for a week or more.  I particularly like this shade, Tutti Frutti Tonga, as it is a soft, wearable pink with a hint of frost.  Although the shade is pale, it is not overly sheer, so 1-2 coats are all that is required.  Definitely a must as a great everyday pink color for nails.
