I was intrigued by the new shatter polish by OPI but I hadn't been able to find it anywhere until this weekend. I had to try it instantly. I had a coupon for a free polish at Ulta so I bought their Professional Nail Laquer in Island Hopper and over layed it with OPI Black Shatter.
The shatter goes on over dry polish and then it shrinks as it drys to give the shattered look. Its not the best image, but its a cool effect.
They have also announced new colors of shatters. I can't find them for sale yet, but I look forward to trying them.
