Set of 4 books A set of 4 word reference books that you can enjoy learning from with story manga. You can learn words in a fun way with cute comics. The covers show some wear as they were used with care by a child, but the books themselves have little damage and should be perfectly readable. The content is easy to understand with comics and is fun to study, so I think children from lower elementary school grades to higher elementary school grades can enjoy them for a long time. Please understand that this is a casual inspection, so there may be oversights. - Title: Idioms Encyclopedia - Title: Words Encyclopedia - Title: Four-Character Idioms Encyclopedia - Title: Proverbs Encyclopedia Thank you for looking.
