Product Description It feels like paper but just try to tear it! This clever billfold is made from Tyvek(R), a synthetic polyethylene material that can be easily printed on. Dynomighty Design has created a line of Tyvek wallets that are sure to raise eyebrows. This wallet has two billfolds and two credit card-sized pockets. Moms take note: Tyvek can be washed should it accidentally be sent through the laundry.
