Thank you for viewing. This is a set of Karakoro Cubes from Wonderbox, a correspondence education program. The booklet content is for ages 4, 5, and 6. Set Contents: ・Karakoro Cubes (16 pieces, with box) ・Puzzle Cards: 8 sheets ・Orange Plate ・Problem Book (Moving Edition) ・Problem Book (Arranging Edition) ・Storage Bag (Bonus: Hatenyan's Puzzle Notebooks, 3 books, filled in) How about this for those considering Wonderbox? There are some problems that link with the app, but it's enjoyable even without the app, so I recommend it. No individual sales, please. As a bonus, I will also include the filled-in "Hatenyan's Puzzle Notebooks." Please use them as a reference when considering Wonderbox. WONDERBOX Wonderbox
