This fabric case can hold card-style health insurance eligibility verification cards, paper-based elderly recipient certificates, credit cards, and passports. *To confirm the size, I've taken photos with my own cards and a passport-sized notebook inside. The product is the case only.* *The cards are intentionally inserted shallowly. In reality, they can be inserted deeply up to 2/3 of the way in (Photos 3 and 4).* There's also a passport-sized pocket behind the card slots (Photo 4). It has been stored at home without being carried around. There is some age-related deterioration.
