Thank you very much for viewing. I am a gagaku (Japanese court music) hichiriki player with over 50 years of experience, and I create over 1,000 high-quality reeds annually. These reeds are made from high-quality reeds harvested from Udo, carefully selected and dried in the shade for about 1.5 to 2 years. They are then smoked over a hearth for over 10 years, making them incredibly durable and possessing excellent sound quality. I believe these are top-of-the-line reeds. Please refer to my past reviews to understand the quality of my reeds. They are finished with great care, allowing for comfortable playing. While they generally fit any hichiriki, including those with plastic tubes, I can accommodate requests for thicker or thinner reeds. They are finished so that even beginners and women can play them easily. However, please be aware that they will not sound with a light breath. To produce a good sound, you must put effort into blowing with a strong breath. The price of one reed is a bit high, but I will handle returns and exchanges if you are not satisfied. I am confident that you will be satisfied with these reeds, so please give them a try.
