Review (5/5): but it's a waste of time and money
I've been doing my own nails for over 30 years and tried every expensive and cheap topcoat out there. This is the one. I bought it in Italy in 1992 having never heard of it and have been going out of my way to find it ever since. Worth the price. I keep trying other brands (Essie, OPI, Orly, etc.) hoping to find something easier to procure that works as well, but it's a waste of time and money. Mavala ColorFix is the only top coat for me.
