KATAMINO A wooden educational toy for ages 3 to 99. ● Condition: Purchased on Rakuten in December 2025 for 6,600 yen. Upon opening, I realized I had mistakenly purchased this instead of a related product from the same company, so this item is no longer needed. I realized my mistake after opening the box, so I did handle the contents, but I have never played with it. I don't think there are any noticeable scratches. Both the outer box and the problem book are in very good condition. Please refrain from purchasing if you are concerned about home storage. ● Package Size: Length: 20cm Width: 33cm Height: 4.8 cm ● Included: Japanese instruction manual, learning book Excerpt from the purchase site: This is a puzzle game where you combine various shapes of pentomino pieces to fill in the designated spaces.
