These paper wallets made by Tyvek are actually made of “thousands of long plastic fibers creating a surface that is both lightweight and durable yet super thin and tear resistant” says dynomighty. They add, “A secret storage area can be used by pulling out the tucked in flaps from the ends, place your things inside and re close the flap back over them.”

The wallets are also printed to look like other materials giving you an added degree of stealth. The wallets are made of 25% recycled materials that are 100% recyclable and at $7.50 a pop, they are really cheap.
