This is a bow I bought as a spare. Although it's unbranded, I judge it to be overall equivalent to my original main bow, the Sforzand (57,200 yen). By "overall equivalent," I mean that it has its strengths and weaknesses compared to the Sforzand. Compared to the Sforzand, I believe this one is made of pernambuco, judging from its elasticity. 71g It feels heavier than the Sforzand (72g), but it's not a big deal. Because it feels heavier, I feel like the sound resonates better. I'm selling it because I bought a higher-class bow.
