These cards are simple and easy to use. On one side is the name of the state, and a map of the U.S. with the state highlighted on the map. On the other side of the card is the name of the capital and a map of the state with the capital marked. Very simple and basic. It doesn't include any other information on the card like many other sets do. But when you need to memorize your states and capitals, this set is exactly what you need.
There are also 34 country cards which list the name of the country on one side, and the capital of the country (with a map) on the other.
