The Kaizen Craft is an exceptional Kendama on so many levels. The Slim is the thinner of our 2 new shapes and boasts several improvements over the original Kaizen. This Kendama was carefully designed by the Kendama USA team, and every single piece is hand finished by Kendama players right here in the USA. The Slim is a slinger machine with amazing lunar balance. This ash wood Kaizen Craft features 2 burn lines added to the tama for improved tracking. The extraordinary level of detail, craftsmanship, and care results in a Kendama you’ll love to play.
