It's a rubik's cube, dude! But don't worry about solving it as the sides don't move and it's all one color. Also, note: this is a rather large cufflink due to having half a rubik's cube on your arm, so it's certainly a statement piece. You are going to have some interesting conversations spur out of this cufflink.
Note: This is a single cufflink! Mix and match with two different colors or different nerdy other pieces. Get weird, dude!
