OPI Nail Lacquer Thinner
Thinner nail polishes apply easier and smoother. As nail polishes age, they begin to clump and thicken. Thinning older nail polishes gives new life to your paints; keeping them smooth and easy to apply no matter how long you've had them.
Just add two drops of OPI Nail Lacquer Thinner to any nail polish for thinner, smoother, and easier to apply nail polish!
