Tomoe brand 23cm abacus drill, perfect for learning. - Brand: Tomoe - Size: 23cm - Product Name: Abacus Drill Thank you for viewing. My grandfather prepared this for my child, but they said they would use their grandmother's, so I am selling it. I will pack it carefully and ship it via Yu-Packet Post! The outer bag and abacus case will be folded in half and included. I think it will be used in elementary school classes, and I hope those who are thinking of learning the abacus from now on will find it useful☆ Thank you very much! ※The outer bag has some scratches, but there are no scratches on the abacus itself.
