Rigabudo's eye was born out of a design by an artist friend named... Rigabudo! This picture shows the anatomy of the eye and is a popular gift for opthamologists and anatomy students. It measures 4" x 2.5" (10,16 cm x 6,0 cm) when closed and can hold up to 20 business cards, or a combination of business, credit and id cards in the two inside pockets. Made from a durable recycled paper and plastic laminate combination and then hand sewn with cotton thread, this card case is a practical and chic way to carry your credit cards, business cards and even cash. It provides a great alternative to a bulky wallet or purse when going out at night. Simply fill it with the few cards you need and a little cash and you're on your way.
