The Sushi Wallet.
The Sushi Wallet is a minimalist, slim wallet made of a 3 inch strip of heavy-duty elastic with a colored trim edge. It holds anywhere from 2-6 cards comfortably (but I'll admit, I cram more than that into mine) and has a cash pocket in the front with a bottom seam to keep your money from slipping through. I've continued to work on prototyping, design and materials to make the Sushi Wallet a high quality product. Since the demand has surpassed what I can handle on my own, I decided I will take the Sushi Wallet to the next level one way or another.
