This is what I call a nail polish lifesaver.
I've used nail polish remover and other cheap nail polish thinners but OPI has the best thinner HANDS DOWN.
Although the price is just as much as a bottle of OPI nail polish its worth it considering the nail polishes this thinner has saved me. I still have tons of older nail polish that I like to use for decorating my nails but some have unfortunately turned dry. However this product helps to make all my older nail polishes look like new!
That's a plus in my book.
