Kumon Tonkoro Gattan (K.K.) Kumon Publishing This is the KUMON TOY Tonkoro Gattan. The outer box doesn't have any major damage. It has been played with regularly, so it's not without scratches, but in my opinion, it's in good condition. I think there are no particular problems for children to play with.
