I have tried several kinds of Sally Hanses nail polishes, and each one was very good, doing exactly what it had promised. Recently, I bought a bottle of Sally Hanses Diamond Strength No-Chip for the first time. It comes in a curved 0.45 fl.oz. bottle that has a small "diamond" on the front - very easy to recognize. The color I chose is very gentle pink, I am not sure what it is properly called as I do not see any name on the packaging except #78.
The manufacturer recommends to apply three coats; the first one needs to dry, then you apply the second one, then wait for 2 minutes and do the third one. I followed these directions and achieved neat results: smooth, evenly coated nails. The No-Chip claim proved to be true, I wore my manicure for over a week without any chipping at all. When this nail polish is put on, it stays on. You'll need to redo your manicure only because your nails grow, not because the polish cracks and chips away.
