Why is it called The Mighty Wallet?
The Mighty Wallet is tear resistant, water resistant, expandable and recyclable. 

What makes it Mighty?
The Mighty Wallet is made from Tyvek. Thousands of high-density polyethylene fibres are spun in an inter-locking fashion to form Tyvek sheets. These sheets are die cut and folded to form a wallet. The origami design further adds to the strength and the tear-resistant nature with no stitching involved in the end product. The folded construction allows these very slim wallets to expand to your personal needs. Check out these videos to see for yourself:
