The Mighty Wallet is the perfect gift for the guy who has everything and it even has an actual size ruler at the top and bottom in centimeters and inches respectively.

The Mighty Wallet is made from a single sheet of Tyvek®, making it a super slim wallet alternative to bulky wallets.

The origami design reinforces the inherent strength of the Tyvek material itself, doubling with each fold. This way there are no parts or pieces that can be removed or torn.

Mighty Wallet! The original Tyvek® wallet invented by Terrence Kelleman in 2005 and has become recognized world wide as a fun sustainable/vegan alternative to traditional leather wallets. Working as a struggling artist at the MoMA Terrence had his first idea for a link-less magnet bracelet which launched his company to "YouTube" fame when his first video went viral and he left his day job to take his shot at becoming a product designer. Since 2002 many of his inventions have been sold in Museum Stores, Gift stores and Design stores around the world becoming an "Inc's Fastest Growing" company in 2010-2012.
