Mine is see-through with liquid inside that causes pink heart glitter to flow back and forth. I always wanted one with liquid inside. It's fun to move around and squish!
I’m currently using the blue Otterbox case for these type of IPhones. Link
It’s a decent case for it’s price. I’ve dropped my phone a few times and didn’t see any dents or cracks yet. What I don’t like is that the rubber part of case is starting to loosen up a bit. I’ve had this case since July of last year.
I have a clear case on my phone, I put my school I.D into the case, so that I can scan the barcode easier. My first phone had an icecream sandwich case, then I swapped to a totoro one. My second phone, had a clear case with my school I.D in it. I used to have stickers inside of the phone along with my card, but they started losing color, and looked really bad.
