Man with Two Faces literally has two faces. This thermal is a bright purple when cold to represent Quirell and his turban and a crimson red when hot for Voldemort and his red eyed stare hiding under said turban. This thermal is also filled with red and silver holographic glitters that sparkle and shine no matter the color change.
*Please note that extreme heat can prevent a full color change or even completely break the polish's ability to change color. I have never had problems with this particular polish but please be aware that shipping is at your own risk during summer months and/or heat waves.
This polish is part of the Harry Potter inspired Book 1 collection.
