Recently, I somehow came across a lot of pictures and video's of colour changing nail polishes. I own two polishes that change in the sun, one that glows under black light, two glow in the darks and one 'mood polish', that changes with the temperature: Mia Secret 'Pink to Peach'. I realized that I only wore that last one two times max (maybe just once) and I thought: why not give it a try again?
