GOKI of Germany makes wonderful wooden toys for children.
GOKI’s Thumb Harp (or Kalimba) is a lovely musical instrument with soft soothing notes. Children and adults will love the sweet sounds produced by “plucking” the metal prongs of the Thumb Harp with thumbs and/or forefingers. The sounds are as gentle on the ears as the hands, with each notes amplified and mellowed as you feel it vibrate the solid wood base. And – by loosening the 2 screws, you can tune the Thumb Harp to different keys!
Thumb Harp measures approx. 22.5 cm / 8.8″ long.
