Material: Wood Cost: Approximately 90,000 yen Thank you for viewing. This item was purchased to improve my scoliosis when I was a student. I am selling it due to moving. If no one takes it by March, I will sadly have to dispose of it. I hope it reaches someone who is suffering from similar symptoms. Thank you.
