Nope, it’s not a envelope or some new fangled notebook sleeve. This my friends, is the Mighty Wallet. It’s constructed of the same material used to produce Fedex’s packing envelopes. If you’ve ever attempted to rip those, then you know how strong the material can be. The wallet is available in a variety of designs, and according the designer will suit most users needs since the material expands as more stuff is inserted.
You can get the Mighty Wallet here for $15.
