I wore another one the Rimmel Pro polishes in Balmy Blue last week. I can safely say that the formula and quality of those polishes are some of the best in the drugstore. The quality is OPI quality and I'm so serious about that. OPI polish loves my nails but not my pockets. I still have several old OPIs because I've only wore a $8 polish once and I refuse to throw it away.
But at $3, I must go and get a couple more Rimmel Pro colors. But trust, I'll be wearing a $3 polish more than once. The principle is the same for me.
