Those are made by Jittendra of Sitara.org He's some guy who lived in India for a lot of years. His stuff is very ornate and beautifully finished. Unfortunately, they aren't really very playable. He's a "concept guy" who is really into statuary and fancy carving, but not to taken seriously as an instrument builder. This is the consensus of professional musicians that have tried his stuff. Buyer beware on this one.
