Here are three sets of children's karuta (Japanese card game) that I used a few years ago: ○ Wonder Story Karuta You can learn about folktales from around the world through this karuta. The back of each card also has a summary of the story. * You can also play rock-paper-scissors on the back. ○ World Flags Karuta You can learn about flags from all over the world, along with the origins of their designs. You can see the capital cities and famous buildings on the back of the cards. * No instruction manual ○ Hiragana Animal Matching Karuta You can learn about various animals through cute illustrations. There's also a lot of trivia. I've played with all of them many times, but there are no noticeable stains or scratches. (Just some tape residue) They are in good condition and can be played with without any problems. Please feel free to ask if you have any other questions.
