RICO Grand Concert Select Evolution Rico Grand Concert Select Evolution Reed for B♭ Clarinet Size 4, Unfiled Cut New, Unopened Size 4, but personally, it felt similar to Vandoren V12, 3.5 (3 1/2) in terms of playability. It seems Vandoren prices will increase to 6250 yen in November, so how about preparing for the price increase? Those who use D'Addario, why not give it a try? I have some in stock, so please feel free to comment if you are interested.
