My son, who is in his final year of kindergarten, has used this a few times. As shown in the photos, the red and black strings have a few snags. There is one scratch and a black line on the box. Other than that, it is clean and can still be used. Recommended for kindergarteners and nursery school children to develop their thinking skills and concentration, and also for practicing for elementary school entrance exams.
