This is not a plastic product. With one set, you can use it for a lifetime. Wooden, authentic Kendama * The length of the string is adjusted to the optimal length by making two knots on the string. As it is a wooden Kendama, I think it also has value as a traditional Japanese craft. * The Othello game had a problem with the lid, so it has been repaired to be usable. I think it will cost at least 650 yen for shipping and Mercari fees, so I don't think it's expensive.
