To Have and To Hold Origami Phone-Back Wallet

You never go anywhere without your phone or your wallet.  Why not join forces, and may as well be cute while you're doing it.  Obviously.  Oh, and bonus, there's a strong elastic strap so you don't drop the aforementioned necessities for living your best life.  Win/win/win.

Comes with pre-applied 3M adhesive for super stickiness.  Easily cleaned with a damp cloth.  And works for both righties and lefties! 

Now the tough part - Platinum or Gold?
