Creepin' ain't easy. It's one of the hardest things to do, because it's all about the subtlety. Scaring people out of their minds is easy, you just have to run up to them with a gross bloody mask and roar really loud. But how do you truly creep someone out... interesting question, right? While we don't have step by step instructions on how to do that, we think that these contact lenses are a great start. They have big slices of black, just like a cat, with green irises. So go forth, young creeper, and give everyone the willies this Halloween!
