Purchased a few years ago. Compared to a standard barrel with rings, this model has a smoother blowing feel and a fullness unique to it. Because it's a shorter barrel, it should also suit those who use mouthpieces and instruments that tend to have a lower pitch. As of November 2025, the list price is 29,150 yen. ~From the manufacturer's website~ Like its full appearance, this is an excellent barrel with a rich sound and moderate resistance. By intentionally not attaching rings, it conveys the player's musical expression more directly.
