Handpan vs. RAV Drum Comparison https://youtu.be/D_4gNgIPU6Q 
This instrument is the same size as most Handpans, and has up to six partials tuned per note. The central note (Ding) has 6 partials, other 8 notes each have 4-5 partials that's why this instument has rich powerful clear sound with a deeper chamber.
Made for playing with hands. The colours can be different from the pictures
