Before we even discuss the Insta-Dri, let's address this brush.... ....whoa. My only thought is how stupid all other nail polish brushes seem in comparison. This thing is wide enough to coat an ENTIRE nail in one swipe- that alone has sold me, if only for the convenience of having one good even coat in one try. I love it, I love it, I love it. Secondly, I love shimmer. It's cute as heck. Enough said. And lastly, yes, it for real dries super fast. So maybe implying that it dries instantly is a bit of a stretch...it's more like 20-30 seconds.....but compare that to 10 minutes between each coat of any other nail polish. My friends, those days are in the past. As an adult human woman with a busy life and other problems, the fact that I took the time to create an account on this website to review this nail polish should assure you that it will make at least one tiny aspect of your life easier. You can now have adorable nails with seriously no effort and no mess and no smears. I mean, it's nail polish, but it's amazing.
