I don't use Facebook very often — it's a place for me to keep in touch with Canadian cousins and roller derby folk, and that's about it. As such, what I'm about to say seems a bit crazy: I not only found Casetify on Facebook, but through a Facebook ad. In fact, the accessory-maker may win the award for the first Facebook ad I've ever clicked on.
I wish I could say that the copy was enthralling or punny, but it was the imagery that actually caught my eye: Casetify makes clear iPhone 6 and 6 Plus cases with specialized designs imprinted on them, and was showcasing them on a gold iPhone. A gold iPhone, encased in such a way that you could still see the gold underneath. Intriguing!
