My mom wanted something subtle and dark, so I used my (overpriced) magnetic nail polish I got from Sephora in the summer. It is pretty cool looking though, and I have yet to see something so interesting in the world of nail polish (I am not a fan of crackle). I made my mom's ring fingers matte, which looks pretty cool combined with the magnetic effect. This nail polish is pretty hard to photograph, but trust me when I say that in person, it looks really cool.
