Trust Duncan to take a good toy and go one step beyond! The Groove Kendama fuses aspects of Kendama play and yo-yo. The Tama has been crafted with a string groove allowing some pretty crazy string catching tricks! there's also a nice little groove on the base of the handle so you can really mix things up - a whole new world of tricks becomes possible with the Duncan Groove Kendama. The Ken also has the added advantage of silicone stickers inside the cups making tough balancing tricks and catches (think Moonlanding!) that much more achievable. Supplied in neat Duncan style blister packaging.
