This is a karuta set from Rurubu that teaches about national flags and prefectures. Children from lower grades can enjoy learning geography. Please read the following: * The national flag karuta is missing the "mo" card. * The prefectural karuta is missing the "mu" card. * Neither set includes the posters. Other than that, the condition is relatively good, but there are missing cards, so it is being sold cheaply as junk. Thank you for your consideration!
