Used infrequently, and based on my amateur assessment, the contents are generally clean. The box has some soiling. I've marked it as "slightly dirty." Please check the images. ☆ Please understand that this is a used item before purchasing. ☆ I've adjusted the price after checking online retailers, where it was sometimes on sale. ☆ I'm still hesitant to sell this, so please be aware that it may be removed from sale suddenly. The set includes age-appropriate picture cards and wooden puzzle pieces, allowing children to learn while playing at their own pace. Personally, I think the satisfying click when the pieces fit together is a great feature.
