- Set includes: white stone parts, 2 sheets of black paper, string - Product name: Magatama Making Kit - Country of manufacture: Japan Thank you for viewing. This is a bonus item from Benesse. I started making it at the time, but gave up. (Only one corner partially made) I have lost the instructions and they are not included m(_ _)m If I remember correctly, you roughly shape it with the large, coarse file, and then smooth it with the smaller file. Unlike me, I hope that patient children or adults will complete it!
