Shinken Zemi Elementary School Course Challenge 2nd Grade Kuku Song Band Kuku Roulette These items are included. I think these are good for children to practice their multiplication tables. I also recommend them for first graders as a preview. These items arrived in 2025. ● Kuku Song Band I've only used it once or twice, so I think it's in good condition. I have confirmed that it works. Box and instruction manual included. ● Kuku Roulette This is for practicing multiplication tables in the bath. I used it in the bath 2 or 3 times, so I will disinfect it before shipping. You put it horizontally in the bath water and take it in and out, which makes the roulette spin. Then you say the answer to the multiplication problem! For those who understand that these are used items.
