Query: I love OPI!

I cannot say enough about the true colors and long-lasting effect of OPI nail lacquer. I have found over the years that nail polish doesn't usually work for very long before it's chipping or fading. I'm not sure what the difference is between polish, enamel, and lacquer but have found the OPI lacquer lasts much longer than any other I've tried. I have multiple bottles of different colors and have thrown away all the other brands I've bought. That should say how much I love OPI!
