I always use a base coat before applying my nail polish, because I don't want my nails to be yellow. Usually I don't care too much about what kind of base coat I am using, but when I heard about CND Stickey Anchoring Base Coat I just had to try it. Basicly it is a nail polish base that is supposed to anchor your nail polish to your nails. The first thing that I noticed about this product is that it is green. I didn't have any problem with staining my nails but I read on the Internet that some people end up with nails stained green. Stickey even protected my nails from nail polish staining. Did it make my nail polish last longer? The answer is no! For me it does nothing!
