Nfu-Oh 61 is an amazing polish that I received this week in a swap. I was so excited because I never thought I would own one of their amazing holographic polishes so needless to say it was going on my nails within minutes of pulling it out of the package. I have heard that you are supposed to use Nfu-Oh Aquabase or any basecoat that is tinted blue to get the holographic glory to really pop. I didn't use a basecoat at all and had absolutely no problems with it being any less wow. The formula is so easy to work with and I used three coats for the photos below. I also didn't use a topcoat for the pictures either because I was worried that it may ruin the holograph but have tried the topcoat since and it doesn't change the polish at all. I literally could not staring at my nails they just didn't look real any more. If you have a chance to buy or swap for this polish - take it!
