This is a complete set of 11 Ricca no Bacchiri-kun Drills. These are the latest editions, compatible with a sound pen. As a special bonus, I'm also including the basic edition's long passage memory drill, which is not sound pen compatible. This brings the total to 12 books. There is almost writing in them, but I will sell them at a low price to those who are okay with that. Please check the images for the contents. The selection focuses on content that overlaps with Keio Yokohama Elementary School and University of Tsukuba Elementary School. The set of all 11 books is offered at a bargain price, but I can also create a dedicated listing for 3 books for 1500 yen. Please consult in the comments. 【Diverse Learning Content】 This "Bacchiri-kun Drill" includes a wide range of content, such as understanding sounds, memorizing long passages, and learning about rules.
