I like to change my nail polish color weekly. I have about twenty bottles or so and even then get tired of my colors. I like the trends out now with painting one nail a different color than the others, but OPI’s Shatter polish and the nail strips and pen are fun to experiment with. The Shatter polish is good to use because you can’t really see any mistakes. And I got so many compliments when I did the Sally Hansen polish strips. It’s a fun trend right now and it’s ever changing so I just match my polish to my mood that week.
