I don't know for sure.
But I bet it wont work together. The Vaja has a very good fit. Meaning it fits snug because it's well made. The invisible shield is very tacky on the outside(not sure if that is the word I'm looking for or not). If you slide the Vaja over the Invisible shield you may not get it off. Unless the Vaja is inserted differently. I am not to sure about that case for Macs, they are great for phones but way to rich for my blood so I've never actually seen one.
I would hate for you to spend all that money and they not work. It is kinda pointless to have them both on at the same time, seeing how they both do the same thing.
Anyway,I hope someone here has them both and can answer your question.
