A fiberglass yidaki, around F.
Weight is solid, not the heaviest but the walls are pretty thick, the look is quite impressive and it's a solid workhorse, easy to play, the toots come with almost no effort, the mouth is too me just the right width, and it goes thinner a bit like a trombone mouthpiece.
Dents can be obvious as below the dark finish they leave a clear spot.
It's an unbeatable yidaki for the money, doesn't need much care and handles extremes conditions compared to a wooden stick ; phases sound excellent. Overall the sound might be a bit synthetic compared to an excellent wooden stick but only a trained ear will note and it's all about taste. To me, it's perfect, I'd totally buy it again if needed.
