Everything is included!! Limited edition guidebook included!! There is some slight soiling on the corners of the outer box, but the contents are clean. Please check the photos. Feel free to ask for additional photos in the comments! A brain-training game using colorful puzzle pieces. KATAMINO is a puzzle toy made up of 12 building blocks called pentominoes. What's surprising is that the target age range is wide, from 3 to 99 years old. If you insert the bar (slider) that divides the puzzle board into the 3rd groove, it's a simple puzzle with only 3 pieces; if you insert it into the 5th groove, it's a puzzle with 5 pieces; and if you insert it into the 12th groove, it becomes an extremely difficult puzzle that no one can clear! The ability to change the difficulty is its greatest feature. It also comes with an easy-to-use problem book, and the total number of problems is 500, and there are 36,057 answer patterns. It's a puzzle that can be enjoyed for a long time, starting from 3 years old and potentially lasting until you're 99. Recommended for children, adults, and as a gift for grandparents. - Product Name: KATAMINO - Target Age: 3-99 years old - Contents: Puzzle pieces, answer book - Design: Colorful puzzle pieces - Brand Name: KATAMINO
