I like to use unique color combinations with my pedicures to keep things interesting. I always want to know how I did with each color combo too. Whenever I get one that I am just not sure of, I make a call to test it out. I have to know if the colors are "prostate approved". LOL! I just wasn't sure about the gray. My foot guy was like, "ehhhh". So, I told him, "with sparkles," and he was like, "really? Let's check this out." It was prostate approved. LOL! Then I saw it in action....on me....yeah, I liked it just fine. LOL! Of course, I could be a little biased.
