Manta Hard Wallet

The Manta hard wallet is a hard case credit card holder. I designed this because I noticed that the only part of my traditional wallet being used was the credit card holder, while the cash and change pockets were barren wastelands.

**Warning** -- this design employs a solid spring mechanism to clasp and contain the cards that is untested. I'm ordering my own copy and I'll update this space when I know for sure that it works.
