Happy Holo-days (or "Holo-day actually)!
Today is Happy Holo-days on Makeupalley's nail board. It pretty much just means a lot of people (including yours truly) are wearing holos. My holo is Nfu-Oh #63. I adore the Nfu-Oh holos. The application is utterly terrible, but they just look sooooo good on. They are without any doubt the most holographic polishes I own.
#63 is very similar to #64. I think you'd have to wear them next to each other to notice the difference. Obviously the holo effect on both is amazing. Close up:
