It's a dual kalimba. (This is not the Pro version, which allows for changing tones, so it has only one built-in tone.) Please be aware that it is made overseas and has some scratches. It's made of Walnut wood. This is a new type with rounded key tips. It is new and unused, but please understand that it is made in China and has some minor scratches before purchasing. I have confirmed that all notes up to the highest pitch sound through the earphones. It is tuned and ready to use immediately. I will ship it after confirming its operation. Scratches can be seen on the body and keys. Please also be aware of the dirt inside the case and the crushed box. / The April Yang Board Kalimba 17 Key offers rich sound quality and can be connected to an external speaker to amplify the music. It also enables a musically dynamic performance. Perfect for players of all levels.
